i had this problem initially after upgrading from 9.2 to 10.0. not the exact same packages you're talking about, but other KDE packages that wouldn't install from the update source due to similar dependency issues. what i did was, i went to MCC->remove software & did a search for KDE. i found quite a few legacy 3.1.X versions of various KDE apps & libs. nothing system critical, mind you, that would hose KDE if removed. i removed (uninstalled) all KDE 3.1.X apps, then tried the updates again & they all worked. so, i'd suggest looking to see if you have any older KDE 3.1.X stuff still installed & uninstalling it, then try your updates. in theory, the upgrade should have taken care of this, but i think it didn't due to the missing MDK disk 4. that contains a bunch of KDE stuff on it. also, after you're done with updates, set yourself up with a "main" source from
EasyURPMI , go to MCC->install software & type KDE in the search. you may be surprised at all the things that aren't installed with the 3 CD download set. the main source contains all the missing disk 4 stuff.
