Wow.  That's pretty impressive.  I'm definitely going to steal some ideas 
from that for setuptools, especially the flag to indicate that an extension 
is optional; I could really use that for certain of my packages.

I had already been thinking of adding a facility to build_ext to look for 
needed includes and libraries, but you've certainly put more thought into 
it than I have so far.
