Erm, probably, but if what you want to do what you describe below,
there's a better way.

Probably the best thing to do is derive your own subclass from
distutils.command.build_ext and override build_extension() to do what
you want, eg:

from distutils.core import setup
from distutils.command.build_ext import build_ext

class MyBuildExt(build_ext):
    def build_extension(self, ext):
        build_ext.build_extension(self, ext)
        # your stuff goes here

setup(....

      cmd_class = {'build_ext': MyBuildExt})

You'll probably want to read the source of build_ext.build_extension
to find out how to get the information you need.

HTH,
