You're using a Fink Python here, but you're looking at the shared  
library and headers for the Apple distribution of Python.... you need  
to be looking at /sw/include for the header and /sw/lib for the  
shared lib, or you need to stop using Fink's Python.  You're probably  
using a SWIG that was built for one of them, but using it against the  
library/headers of the other.
