rpy2 installation error (OS: linux mint 17 | R 3.1.2 | python 2.7.6) - rpy2

Question

When I run 'sudo pip install rpy2' I get the a lot of compilation errors.
Here is the full dump of all the errors and here is an example except:
Compilation parameters for rpy2's C components:
include_dirs = ['/usr/share/R/include']
library_dirs = ['/usr/lib/R/lib']
libraries = ['R', 'pcre', 'lzma', 'bz2', 'z', 'rt', 'dl', 'm']
extra_link_args = ['-Wl,--export-dynamic', '-fopenmp']

Some background. Previously botched the installation of ipython notebook dev version and have reverted back to the pip repository version. Not sure if that plays a role. Was able to get R magic working a little before that.
I had made sure to run 'apt-get updates', 'pip uninstall rpy2', 'apt-get purge python-rpy2 && apt-get remove python-rpy2' before attempt to re-install. To check if there was any residual files, I ran 'import rpy2' in ipython and that resulted in an module not found error (good, nothing was lingering).
Not sure where to begin troubleshooting. Advice is appreciated.

It worked after installing the following dependencies:
apt-get install libreadline-dev
apt-get install r-base r-base-dev python-dev python-setuptools

Answer 1

You need the headers for the readline library:
apt-get install libreadline-dev
