I can think about www/webkit-gtk and www/webkit-gtk3 in this case, for 
which packages relying on either one would probably have to explicitly 
include the proper one, depending on which version of Gtk+ is preferred 
in the first place.

Well, for wip/deforaos-libdesktop (on which 13 other packages depend), 
the switch to Gtk+ 3 is only a matter of changing the inclusion of 
buildlink3.mk from either x11/gtk2 or x11/gtk3 (and then webkit for 
deforaos-surfer as mentioned above).

This might affect more than just the software I've been writing myself, I 
just have no idea how many would be relevant; if there are "enough" I do 
think it would make sense to be able to switch between Gtk+ 2 or 3 from 
mk.conf.
