But that's not what happens at all.  By doing:

USE_GNOME=	gtk20

All you're saying is that I want this port to use GTK+-2.  You're not
bringing in any additional GNOME components at all.  The same is true
for the gtk12 component.

I don't see how this is the case at all.  If you want to experiment,
take a port that only uses Gtk+-1.2, remove all the USE_GNOME stuff, add
USE_GTK=yes, then do a make package-depends.  Then, replace USE_GTK=yes
with USE_GNOME=gtk12, and do the same make package-depends.  You should
get the same thing.
