Cabal install package fails weirdly - haskell

I access internet through a proxy and have appropriately set up the environment variables. The problem is that whenever I am trying to install any package through cabal, it fails with a
connect: does not exist (Connection Refused) error.
But if I run cabal update -v3, it successfully makes the connection and retrieves the update information.
$ cabal --version
cabal-install version 1.20.0.2
using version 1.20.0.1 of the Cabal library
Edit: I'm running Ubuntu 14.04.

Okay. The problem is solved by using -E with sudo command.
sudo -E cabal install <package>
Although, I don't understand why cabal update could work but not cabal install.

Installing octave in termux, "Unable to correct problems, you have held broken packages"

I am trying to install octave from the "Its Pointless" repository mentioned in the termux wiki. The repository is added successfully as far as I can tell. However, when I try the command pkg install octave I get the error "octave Depends openblas" "octave Depends arpack-ng" "Unable to correct problems, you have held broken packages"
I have run dpkg --get-selections | grep held but it doesn't return anything.
When I try to run pkg install openblas it gives the error "openblas Depends libgcc but it is not installable"
When I try to run pkg install libgcc it gives the error "package libgcc is not available but is referred to by another package, this may mean the package is missing, has been obsoleted, or is only available from another source. However, the following packages replace it: ndk-sysroot"
After searching some more I did pkg install clang but I still get the same errors. ndk-sysroot has been installed during installation of clang.
I have done apt-get autoclean, apt-get autoremove and apt-get purge but that did not do anything.
What can I do to fix this problem and install octave on my phone?
The problem got solved by itself.
I tried pkg install octave again and got a response saying "The repository https://termux.net stable Release is no longer signed."
So I ran the command bash setup-pointless-repo.sh again.
And that was it! pkg install octave is now working.

"configure: error: libnl and libnl-genl are required but were not found"

I'm trying to configure powertop-2.5 but when I run ./configure I get a "configure: error: libnl and libnl-genl are required but were not found" error
I've run
sudo apt-get install libtool autoconf libnl-dev ncurses-dev pciutils-dev build-essential -y
as was recommended by these guys but I get the same error.
I ran
sudo apt-get install libnl-genl-3-dev
Which replaced the previous libnl file but I still get the config error.
According to this, powertop has (or had) problems with detecting libnl but I can't figure out how to fix it.
I'm currently running Linux username 3.2.0-4-686-pae #1 SMP Debian 3.2.51-1 i686 GNU/Linux
I see you tried libnl-dev, maybe try libnl-3-dev instead:
sudo apt-get install libnl-3-dev libnl-genl-3-dev
Probably the problem is the lack of the pkg-config application in your system (which is used to find the proper dependencies with the configure script). I just have the same problem in a fresh installed Ubuntu 14.04 system, and after installing the pkg-config package the configure script finalized successfully its work. Then I could compile and install the last version (2.6.1) of powertop.
I "solved" my problem by installing powertop-2.0 instead.
The use of pkg-config made the trick. I was able to install Powertop 2.7.

Error installing charlock_holmes : Error installing GITLAB

Someone, can help me debug those logs and error?
This looks like issue 1952
It was actually weirdness with the way my ubuntu VPS is commissioned. Mine did not come with a C compiler or libdev obviously.
The problem fix I found was to install libdev first, then the GCC
Then apt-get install libicu-dev.
Update 2015: additional comments include:
yum install libicu-devel worked for me
You just need to make sure "patch" is installed (yum install patch) then it should work
For MacOS install the following dependency:
brew install icu4c
According to the documentation (https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/installation.md) the package libicu-dev is required
Install it with "apt-get install libicu-dev" and then charlock_holmes could be installed
I used "yum install libicu-devel" and then I could install charlock_holmes
I got the same mistake on a Centos 5.4 server, the yum repository only have the icu version 3.6, so i have to search and install manually the library icu 4.2 which solve the problem. In case someone else need to know how to do it, i recommend to check this link http://source.icu-project.org/repos/icu/icu/tags/release-4-2-1/readme.html#HowToBuildUNIX
I had kind of the same problem: when I was trying to install charlock_holmes gem, I had this error:
charlock_holmes-0.7.3/mkmf.log
have_library: checking for main() in -licui18n... -------------------- no
I fixed it by running the first command of #VonC:
sudo apt-get install libicu-dev
Hope I helped someone!

How to fix Error 2 when trying to make haskell-platform?

I downloaded the Haskell-platform source from here: http://www.haskell.org/platform/linux.html, installed ghc, and did /.configure. However when I do sudo make, I get the following error:
Preprocessing library HUnit-1.2.4.2...
Test/HUnit/Base.hs:1:1:
Could not find module `Prelude'
Perhaps you haven't installed the profiling libraries for package `base'?
Use -v to see a list of the files searched for.
Error:
Building the HUnit-1.2.4.2 package failed
make: *** [build.stamp] Error 2
Does anyone knows how to fix this?
I'm trying to install on Ubuntu 12.04.1 LTS
Instead of trying to install from the sources, simply install the Ubuntu packages, which will be much simpler, with:
$ sudo apt-get install haskell-platform
If you need a local version of the documentation and the profiling libraries, install the additional packages with:
$ sudo apt-get install haskell-platform-doc haskell-platform-prof
Daniel Fisher's comment led me to the solution. You have to install all the profiling libraries for each of the ghc packages you have installed.
Just write
sudo apt-get install ghc*-prof
That's how it worked for me

Trouble installing Timeplot in RHEL

When installing Timeplot in RHEL 6 using the following command
cabal install timeplot
I get the following error:
Data/Array/IArray.hs:1:14: Unsupported extension: Trustworthy
To install timeplot I needed to install the haskell-platform and cairo-devel package (from EPEL) with
sudo yum install haskell-platform cairo-devel
Then install gtk2hs-buildtools
cabal install gtk2hs-buildtools
Open a new terminal at this point to get the new $PATH that includes $HOME/.cabal/bin
You many need to manually install strptime-1.0.6, as strptime-1.0.7 gave me the following error
building strptime-1.0.7...
Data/Time/Parse.hsc:22:18:
Could not find module `Foreign.ForeignPtr.Unsafe':
Use -v to see a list of the files searched for.
Install strptime-1.0.6 with
cabal install strptime-1.0.6
Then install timeplot
cabal install timeplot
Timeplot probably depends on a newer array than what comes with the installed GHC or platform, and thus it tries to pull it off hackage. And the new array (that is selected by default) is not backwards compatible with older GHCs.
