disappeared in the KDE distributed with Fedora 10?
yum -y install kcontrol
No package kcontrol available.
I still find it on my Red Hat 9.
I yummed kdeadmin, but it doesn't seem to install kcontrol, which it should provide at least as per:
The KDE Control Center. also known as KControl, is the centralized settings manager for the KDE desktop environment. It is part of the kdeadmin package.
