hmm, sounds as if the size is more determined by the shared lirbaries
you depend on (wxWindows, GL, etc.) rather than the python wrappers.

yeah. But that doesn't help you strip down the C++ libraries. For those
you have to repackage the original libs (or at least use static libs 
whenever you can).
