And here is the real problem:
Sg won't work with python-gtk linked against GTK-2.0!!!
I supposed to think the previos GTK-2 calls come here...

... because here sg uses GTK-1.2 again...

So the only thing you can do  is grab a python installation  with python-gtk 
linked against gtk-1.2 and the numeric python module and after all compile SG 
against this python.
