Thanks to the PSU's time machine, I answered your question before you asked it:

Your setup.py file might look like this:

#v+
from distutils.core import setup, Extension

setup (name = "pa",
       version = "1.0",
       maintainer = "Alex Martelli",
       maintainer_email = "aleax at aleax.it",
       description = "Sample Python multimodule package",

       ext_modules = [Extension('pa',sources=['pa.c'])]
)
#v-
