I installed GNOME 2.2, but I am missing application foo. What gives?
Only the core components, and a few extras, are included in the gnome2 package. While you can still run GNOME 1.4 applications under GNOME 2.2, a number of applications have already been ported to GNOME 2.2. The applications that have been ported are included in the gnome2-fifth-toe meta-port. Note, some of these applications are still in the early development stages, and may not be very stable.
