Add remove packages/ packages not found - bouncing icons removal

[j]

I'm runnin Core 2 Test 2. and had to load and install most of the .rpm's 
because the iso's wouldn't work. Now, when I run redhat-config-packages, 
select the X11 , Kde, and Gnome development tools, it says that I need 
xorg-x11-libs/kdelibs and kdebase. I do a rpm -q on these and I have 
them installed, probably newer versions than what's in the rpm database. 
How do I get config-packages to recognize the installs?  As an aside, 
how does one remove those absurd bouncing icons?
thanks,
