Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.
You have not said how you are trying to install KLogic
. It sounds like you may be attempting a Source Install
without having the dependencies installed. From the home page it appears it has not been adapted to KDE4 yet, so it may not work for CentOS-6.
The best approach is usually to read about how to rebuild SRPMs
and find a SRPM as a starting place. Unfortunately I don't see any for RHEL/Fedora - only SuSE and Mandriva and derivatives. It is listed on the Fedora wishlist
