Installation failure

From readthedocs/readthedocs.org#2707:

I tried to install your library locally and failed:

Perhaps some issue configuring the environment variables?

[molpopgen]

Can you try it in a fresh condaenv with the bioconda version of gcc, which is pinned at 4.8.5. I'm also not sure what system you are using (os x? linux?)

Also, the pip command is incorrect--see the README.

[astrojuanlu]

Sorry, I'm using Linux. I'm pasting conda info -a here.
I tried pip install . --upgrade --intall-option=--use-cython from the zip and didn't work either.

The complete list of dependencies are in the .travis.yml, and they are also listed in the readme: fwdpp, cythongsl, cython, libsequence, pandas, numpy.

But, this is not going to solve the RTD issues. The package builds on Travis, so we know that isn't the problem: https://travis-ci.org/molpopgen/fwdpy
