Diez,

I repeat I am a newbie, so please don't be angry against me, if I say
something stupid or if I propose a method not efficient.

An easy way to get the absolute path of site-packages seems very
useful to me, in order to check anything (all extensions available and
not provided by sys.path, etc.) related to the files on the
filesystem, if necessary.

For the automatic installation of missing extensions (using admin
rights), I think that it is not difficult to do it on both
platforms...
