Thanks Helena. The issue that I ran into today (embarrassingly with  
my class) is that of the v.surf.*modules, v.surf.bspline does not  
work (I reported this sometime back), v.surf.rst crashes and brings  
down the entire GUI (this is new), leaving only v.surf.idw as the  
only functional interpolation routine in todays SVN trunk.
