Because of import- and compatibility issues I build everything from scetch some
days ago. Now i only have one Python (2.7.1) installation and only one
matplotlib version (1.0.1). In the
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/
directory there's, too, only the matplotlib dir and the
matplotlib-1.0.1-py2.7.egg-info …
It was build from source; what has to be removed to uninstall matplotlib
completely? Maybe it would help to rebuild it.
Best,
Hannes
