Homebrew-installed Python and the system Python that comes by default
on OSX are binary compatible with wheels generated with Python from
the official OSX installer from python.org.
In current versions of pip you "just" have to rename the wheel
filenames to get them picked up from PyPI on those platforms.
This explains the strange names of the OSX wheels for numpy for instance:
macosx_10_9_x86_64 is the platform tag used by Homebrew-installed
Python while macosx_10_6_intel is the platform tag of the python.org
Off-course if your python extension link to non-system libraries, you
have to embed them in the wheel, for instance using:
