Thanks to the very kind help of the man who develops DeVeDe I have created a revised version of the program that will work on Suse 10.2 until the next release (in which he promises to have the bug fixed).
DO NOT use a precompiled binary of the current release with python 2.5 installed. The current release looks specifically for python 2.4 and freaks out (as you see above).
Download my revised package at:
(the server is slow right now so be patient)
Uninstall any other version using smart or yast or whatever.
Uncompress my file from above, run ./install.sh as root, and run devede from the command line.
Life should be good until the next release appears as a binary in the packman repo (or wherever). Then go back to the directory where you uncompressed it and run ./uninstall.sh before installing the binary.
In the meantime you can add it to your Kmenu if you want...
