pomegranate: Pip installation issues ValueError: 'pomegranate/*.pyx' doesn't match any files

Hello everyone,

First I wanted to say that this repo looks really well done, and I am excited about using the probabilistic models. I know that the maintainers are probably pretty busy, so I am willing to help out where it makes sense with this issue. On my mac OSX, I ran into an issue where I can’t pip install pomegranate. When running both pip install pomegranate and pip install pomegranate --no-cache-dir, I get the following error:

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/jp/sh4l4l4x4vb216bqy49y87v00000gn/T/pip-build-DG1HK3/pomegranate/setup.py", line 34, in <module>

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/jp/sh4l4l4x4vb216bqy49y87v00000gn/T/pip-build-DG1HK3/pomegranate/

I looked at the readme, and it mentioned demoting a couple of libraries, but that didn’t seem to do the trick. Do you have any other thoughts?
