Hi, gnome-control-center is not a fundamental or important application. I agree that probably it has been eliminated by RedHat for unknown reasons. Anyway:
1) It was present in RHEL6beta has shown here: http://www.dedoimedo.com/computers/rh6-beta.html 2) It is present in all Gnome based distributions like debian, ubuntu, suse etc. as part of the gnome environment. 3) In Scientific Linux 6 there is a last residue of this disappeared application: if with "alacarte" you click in Preference Menu and with right mouse button on the "Control Center" item, looking at Properties, you will see a call to the "gnome-control-center" application.
