Oh -- both Darren and I forgot to suggest rm -rf "build" in addition
to site-packages/matplotlib. This is, however, suggested in
http://matplotlib.sourceforge.net/faq.html#FAILURE
The first thing to try is to remove site-packages/matplotlib and
reinstall. If you are running the windows installer or using some
other package, that is all you need to do. If you are compiling
matplotlib yourself, you also need to remove the build subdirectory
of the matplotlib src tree you are compiling from. It is not enough
to do python setup.py clean. Try rebuilding and reinstalling
matplotlib after removing these two directories and see if that
helps. If
Glad you found and fixed the problem!
