[QGIS-Developer] Python modules shipped with QGIS

[Gerald Kogler]

Hi! Sorry for repeating this question if it was asked lately, but I 
don't find anything in the archives.

Where do I find the list of python modules (including there versions) 
shipped with QGIS on different operating systems? I'm developing a QGIS 
plugin and get some error messages like 'No module named...' on Windows, 
but not on Linux and Mac.

Thanks a lot
Gerald
