#4680: [with diff, needs new spkg] matplotlib configuration finds system-wide
files on OSX
------------------------+---------------------------------------------------
Reporter: craigcitro | Owner: mabshoff
Type: defect | Status: new
Priority: major | Milestone: sage-3.2.2
Component: build | Keywords:
------------------------+---------------------------------------------------
The matplotlib install on OSX can find the system-wide files, leading to
problems like this:
{{{
sage: from matplotlib import _png
ImportError: dlopen(/sage/local/lib/python/site-
packages/matplotlib/_png.so, 2): Library not loaded:
/usr/X11/lib/libpng12.0.dylib
Referenced from: /sage/local/lib/python/site-
packages/matplotlib/_png.so
Reason: Incompatible library version: _png.so requires version
27.0.0 or later, but libpng12.0.dylib provides version 23.0.0
}}}
The matplotlib config tries to look all over for libpng, but we only want
it to find the sage specific one. The attached diff of `setupext.py` in
`matplotlib-0.98.3.p3/patches/` tells it not to.
