[Distutils] installing both packages and (sometimes) modules

For the spambayes project, I have a distutils setup that installs the 'spambayes' package. I also (for 2.2) want it to install copies of 'sets.py' and 'heapq.py' modules into site-packages. Unfortunately distutils will let me have a 'packages' line, or a 'py_modules' line, but not both. Is there an easy way to do this that doesn't involve subclassing a distutils command?
