I can do cabal install for c2hs just fine and the other dependencies however my build script just doesn't seem to work on nix-os. let me know if you can solve this. I think I just have something configured wrong.
In the cabal file, you should use the build-tool-depends field instead of build-depends for executables you depend on.

Your cabal is very old, and I strongly recommend you upgrade.
That said... with cabal-1, the invocation is simply
cabal install
with no elm at the end. Run it from within the directory you cloned from github that has a file named elm.cabal or similar -- it will automatically look for a file with extension .cabal and install the package described inside. cabal install will also take care of installing the missing dependencies.
With modern cabal, and assuming the executable named in the .cabal file is called elm, I would use
cabal run elm -- --args --for --elm --compiler
to run the compiler during testing, and then
cabal install --exe
when you are satisfied with your changes and want to make the executable available more widely.

I'm using the Haskell Platform installed using homebrew (brew cask install haskell-platform), and cabal version 2.0.0.2. I have tried using sudo and deleting my ~/.ghc file
There was an issue with full 8.2.1 binary platform builds that's just been resolved: https://mail.haskell.org/pipermail/haskell-cafe/2017-October/127979.html
This was likely an instance of that.
(see also: GHC cannot find libraries on fresh install of Haskell-Platform)
This looks like a bug in Cabal 2 (or potentially GHC 8.2). See https://github.com/haskell/cabal/issues/4728. I'd recommend sticking to GHC 8.0.2 for the moment with either cabal 1.24 or Stack. I'm the case of Stack, the version won't matter, since it will use the Cabal version shipped with GHC.

I don't understand. According to Hackage, sdl2 is at version 1.1, but installing it requires version 2.0.3? I've tried this in and out of a sandbox. Results of ghc-pkg list are here if you think they're relevant: http://pastebin.com/tFrsfPFe
I'm on Ubuntu btw.
Help?
Another thing which could happen (happened to me) for other installs is that the PKG_CONFIG_PATH variable might not point to the package config file (sdl2.pc, for me in the /usr/local/lib/pkgconfig directory). pkg-config uses some default directories ('/usr/lib/pkgconfig' and '/usr/share/pkgconfig'), but if the sdl.pc file isn't in one of these, you'll have to specify the directory in the environment variable. You can check this with echo $PKG_CONFIG_PATH
If it turns out you need to set the variable, just use export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig (or to whatever directory your sdl2.pc file lives in)
I ran into the same problem, and I just want to add my solution here for the record. The native sdl2 libraries need to be installed first by following the directions here: https://github.com/haskell-game/sdl2#building

--reinstalling did nothing.
I even played with the --user and --global flags, even tho I'm using cabal and not runhaskell, it doesn't help it.
I also tried to delete & re-init the sandbox.
I tried just deleteing the sandbox too, and it still gave me the same error.
ghc-pkg check finds nothing wrong.
What could it be?
By the way a part of me is suspicious that cabal ignores that my project is in a sandbox, since it didn't bother to install some packages that were already on my machine; it does so on my Windows (this is on Ubuntu). Is it possible to get that checked?
Ubuntu 14.04.1 LTS
GHC version: 7.6.3
cabal-install version: 1.20.0.3

Also tried now with cabal-install 1.16.0.2 without success.
Package names are case sensitive in Cabal/Hackage, the correct package name is HUnit. Change the line in your cabal file containing:
hunit ==1.2.*
To
HUnit ==1.2.*
