 Sounds good. Thanks. What else were you considering for the gnome
 portgroup, and is there anything you need help with?

 I considered that, but was trying to learn my lesson from the app
 portgroup, in which I turned its functionality on by default. This turned
 out to be inconvenient in situations where some subports or variants in a
 portfile wanted the feature and some did not. Consider for example the
 goffice port. The main goffice port wants introspection, but the goffice08
 subport does not.

 Additionally, if the portgroup were to enable introspection the moment it
 is included, as you suggest, this would mean all ports that use it would
 need to ensure they use `depends_lib-append` instead of overwriting
 `depends_lib`, and `depends_build-append` instead of overwriting
 `depends_build`. This kind of thing is easily forgotten and will lead to
 more problems to be debugged later. If instead we simply require that
 `gobject_introspection yes` is called after the dependencies have been
 added, then we avoid those problems.
