mCalendar quit working after my Diablo upgrade.

As a hint, the entire Python part of the upgrde did not go well. Currently there are not many Python componets that show up in the application manager, either installed or otherwise.

When I go to the khertan.net site and attempt to install the python-hildendesktop package that is listed there I get an Incompatible Package error. I do know there was a Python upgrade from 2.4 to 2.5 included with the Diablo upgrade, but I was wondering where I should go from here, as in what packages and from what repositories should I somehow get installed?
