You can do this with python-support today. See python-cherrypy package
for an example.
Depends: python (>= 2.3), python (<< 2.5)
Declare the minimum supported Python version.
Package installs to /usr/share/python-support/$PACKAGENAME.
postinst calls update-python-modules, which will bytecompile Python
sources to /var/lib/python-support/$PYTHONVERSION for each Python
versions installed. Instead of symlinking, python-support.pth, path
configuration files are placed by python-support package, which extends
Python's module search path.
Path configuration file is documented here:
