Thanks (gmane still isn't showing your response). You have cleared up my misgivings. Since rpm -e allowed me to remove a package, then it must not be required by any currently installed program, and I have likely not damaged anything by removing these apparently unrequired packages, so I need not reinstall them. By the way, I also uninstalled PyQt and PyKDE (I have PyQt4 and PyKDE4) and rpm never complained, so I presume my system does not need them for anything (I am trying to keep my system clean of any old kde3 stuff, as much as possible).
