Most likely our fault. I rebuilt with setuptools-18.0.1 and that
didn't help. Looking at a Fedora 22 system,
matplotlib-1.4.3-py2.7-nspkg.pth is read, but not on our system. This
is the problem. If I move this file out of the way on the Fedora 22
system, the failure is the same as above. Just need to figure out how
Python reads this file.
