mplot3d broken?

While running backend_driver.py on the maintenance branch, I found that the mplot3d examples were not working. Here is an example:

efiring@...340...:~/programs/py/mpl/mpl_v1_0_maint/examples/mplot3d$ python wire3d_demo.py
Traceback (most recent call last):
   File "wire3d_demo.py", line 6, in <module>
     ax = fig.add_subplot(111, projection='3d')
   File "/usr/local/lib/python2.6/dist-packages/matplotlib/figure.py", line 675, in add_subplot
     projection_class = get_projection_class(projection)
   File "/usr/local/lib/python2.6/dist-packages/matplotlib/projections/__init__.py", line 61, in get_projection_class
     raise ValueError("Unknown projection '%s'" % projection)
ValueError: Unknown projection '3d'

Double-check your axes3d.py file. The Axes3D class should have a member variable called “name” at the very beginning of it, and the very end of the axes3d.py file should have two lines of code that registers the axes3d object with the projection system.

Double-check your axes3d.py file. The Axes3D class should have a member
variable called "name" at the very beginning of it, and the very end of
the axes3d.py file should have two lines of code that registers the
axes3d object with the projection system.

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.
