I take it you installed the " live cd" and not the FULL dvd install ?
did you install the "normal" Gnome version or the special KDE version ?
if the normal Gnome dvd then for the KDE tools you need to install KDE desktop
Code:
yum groupinstall "KDE (K Desktop Environment)"
--- for the kde devel tools ---
yum groupinstall "KDE Software Development"
or do you want the Gnome tools ??
see
and do you need a gui ide ?
like Eclipse or Anjuta
