Good to hear.

If you were able to build and install it, then you didn't hit this kind 
of problem. You can test this by running Python and in its command line 
trying: from PyKDE4.marble import *

pyuic4 doesn't know what to do with KDE widgets. There is a little 
program in PyKDE called pykdeuic4 which does know about most KDE 
widgets, but not marble. (You could hack it to support marble. It is 
quite simple.)

The easiest way for you is probably to add an empty widget to your UI 
design and then in your python code replace it with an instance of the 
marble widget at run time.

There is also a small test program in the marble/examples/python 
directory in kdeedu which shows how to get a marble widget going.

cheers,
