On the master branch, MacOSX. I'm trying to build the matplotlib docs. I'm running into a strange latex error when building docs:

RuntimeError: dvipng was not able to process the following file:
/Users/choldgraf/.matplotlib/tex.cache/c1d089b6baf6a9ebfc28a7497a9f3957.dvi

I've tried deleting this folder, and the error still comes up. I installed latex via the mini mactex package. Any ideas what's going on?

Extra tex packages I had to install (via texlive):

• dvipng
• ucs
