New issue 2404: Building matplotlib fails on OSX
https://bitbucket.org/pypy/pypy/issues/2404/building-matplotlib-fails-on-osx
Prabhu Ramachandran:
Am trying to build matplotlib. I have pypy2-v5.4.1-osx64 installed and have
installed the original numpy (from git) which is slow but does work. When I
try to build matplotlib from the latest source or via pip I get the following
error:
```
$ pip install matplotlib

With the git version when I run `setup.py install` I get:
