YIKES -- to think I've had that mistake for years since WhiteBox 
Linux and never knewshu.  Lots of other updates happened, and then a 
reboot to use a new Kernel, and finally KDE installed without a hitch.

Yum/Priorities/Repos maintainer:  Maybe there should be a suggestion, 
or "default" setting of priorities that at least does what the above 
suggests, or comments to that effect in the repo files so others 
won't make the same mistake I did.

Thanks a lot
