I quickly created a dummy deb for python-support. You can try it, but it might not work as the real python-support contains a script update-python-modules that gets called during install of Python modules. It depends on where it gets called on a real Debian system.

EDIT: Tested it, but no go. python-dateutil requires python as well. It also installs its files under different directory than Maemo packages seem to do, so probably not worth it.
