Comment (by c.herbig@…):

 Replying to [comment:15 suv-sf@…]:
 > AFAIU the dependency on py*-gobject needs to be changed to py*-gobject3
 for Python support in GTK3-based Gnumeric.
 Changing the pyX-gobject to pyX-gobject3 will kill the python25 variant,
 there seems to be no py25-gobject3.  I personally am OK with this since
 python 2.5 is obsolete, but I just wanted to mention this in case anybody
 else is depending on it.
