Why not just

import wxPython2_4 as wxPython

and a symlink or something equivalent pointing to the latest version
to also allow

import wxPython

Presenting the user with the choice of two equivalent modules is a mistake
IMHO. Just rename cPickle to pickle and move pickle.py into the
docs/demo/educational section. Or, more general, provide a Python version
as a fallback:

<pickle.py>
try
    # try 
    from cPickle import * 
except ImportError:
    # python implementation
</pickle.py>
