move around in gtk2-perl

[goran kirra net]

I noticed why it sometimes Inline-compiles are very sloooow.
It recurse into all subdirectories, so if you rebuild Gtk2.pm
in an previously built tree all classes are traversed (not 
fully rebuilt though).

Thanks you BUILD_NOISY for letting me spot this!!

I hacked around with the classes Gtk2 Gtk2::Gdk and Gtk2::Pango
too avoid this and it now works and are in CVS.
