In the long term, I'd like to make Pyrex do its own
dependency discovery, and not use a distutils extension
at all. That is, you call the Pyrex compiler from your
setup.py file prior to calling setup(), and distutils
is only used to compile and link the .c files.

It would be nice if distutils could be easily extended
to handle new kinds of preprocessing and its attendant
dependencies, but it appears to be structured the wrong
way for that. So I'm working towards getting out of
the distutils extension business altogether.
