AARRGG! I can't believe they haven't upgraded that page yet. (I'm pretty 
sure I submitted a doc patch a couple years ago!)

When building python extensions, you REALLY want to use distutils. See 
here for an example:

http://www.swig.org/Doc2.0/Python.html#Python_nn6

at least that doc patch got in there.

Let us know if that still doesn't work.
