yast dependencies

Hi YaST reports that I need kdesupport-devel since I updated SuSE 7.2 kde 2.1 to kde-2.2.2. -- YaST1 -- Package 'kdesupport-devel' is required by other installed packages. It should be installed too. How can I find out which rpm package needs kdesupport-devel? I know how to find out the dependencies of a particular package, but not in reverse. Thanks Rich -- Powered by SuSE Linux Richie Rich
