Bitten by distutils again.  Attempting to get a complete clean rebuild, 
I was deleting dist-packages/matplot*, but not 
dist-packages/mpl_toolkits/.  Of course, doing that blows away basemap, 
which is not really what I want.

It would be simpler if everything installed by matplotlib's setup.py, 
and nothing else, would land in a single tree (package).  Having several 
things land in mpl_toolkits, and having other things also land there, is 
a pain.  Maybe we are stuck with it.  Or maybe things like basemap 
should be packages in their own right, parallel to matplotlib, instead 
of being inside mpl_toolkits.
