I cannot import marble from PyKDE4. Even if I have no error reported by 
compilation, I do not see anything indicating that a Python module has 
been created.

I also tried to produce GUI with pykdeuic4 but it failed with the same 
error. Moreover I am not really interested in having KDE libs included 
in my app. I aim to produce a portable executable for both Linux and MS 
Windows. I have read that Marble does not rely on KDE so we should be 
able to get MarbleWidget and pyuic4 working together.

Maybe it will help if you know I am compiling from Marble 0.8.0 
downloaded from http://edu.kde.org/marble/download.php .
