libgtk and libgdk

[nandalal itmin com]

Hi!
I am running RedHat 7.0 and a workstation install in a partition running
windows as well. I am using KDE and not Gnome, and did not make any
selection of packages at install, but let the default install go on.
I am fairly new to Linux but keen to learn.
I find that I cannot run many of the programs(kppp, Xconfigurator, ldconfig
etc.) as the message libgdk-1.2.so.0 not found or libgdk-1.2.so.0 not found
appears. I have found that libgtk-1.2.so.0 is a pointer to libgtk
-1.2.so.0.5.3. This is missing. The libgdk file actually exists on the system.
I added the PATH to the file as well. No luck!
Anyone had this problem?
Thanks for your help
