Ouch! Are they really not using distutils to build the extension modules? Even
when you fix the specific issue above (if you're on OS X, add -lcc_dynamic to
the link line; otherwise, I don't know), you're still probably going to have
other problems. distutils knows how to build Python extensions modules. The
pynovas Makefile doesn't.
