I thought that was pretty much the best option though. For pyrex i did
something ugly like this:
--
versions=2.2 2.3
files=exec1 exec2
set -e; for version in $(versions); do \
  for file in $(files); do \
    python$$version setup.py install --root=debian/python$$version-pyrex --no-compile ;\
    sed -i "s|#!/usr/bin/python.*|#!/usr/bin/python$$version|" \
       debian/python$$version-pyrex/usr/bin/$$file ;\
    mv debian/python$$version-pyrex/usr/bin/$$file \
       debian/python$$version-pyrex/usr/bin/python$$version-$$file ;\
    install -d debian/python$$version-pyrex/usr/share/man/man1/ ;\
    install -p -m644 debian/python$$version-$$file.1 \
       debian/python$$version-pyrex/usr/share/man/man1/python$$version-$$file.1 ;\
  done \
done
--
http://ftp.debian.org/debian/pool/main/p/pyrex/pyrex_0.9.2.1-4.diff.gz

some more questions:

And about the module location, what goes where exactly:
  - usr/lib/pythonX.Y/site-packages
  - usr/lib/site-python ?
Is the second place for modules that do not need byte-compilation ?

There could be a python:Depends to fetch the dependancies of a python module (a
sort of grep ^import *.py) too.

How much problem would it cause to drop python2.1 support?  

Cheers, piem
