Depends on your python binary. IIUC, python and its extensions needs to 
be built with the same compiler. (I recall getting complaints on that 
from setuptools.)

I think Python 2.5 (as released on python.org) was built with VC71. 
Python 2.6 uses VC90, so going there might help.


P.S. I'd wish Python would use something like JNI to avoid this. Would 
make it much eaiser to distribute and use extension binaries. IIRC there 
was a PEP for PNI, but that got voted down. :-/
