Yes, you need to recompile.  It will need to compile _backend_gdk.c, 
which needs to be able to find pygtk.h.

The plain (non-agg) gtk backend is basically unmaintained and its use is 
discouraged.  Are you sure there isn't a reasonably easy way to do what 
you need with qt4agg, for example?  How do you want to visualize your 
million points?
