Description of problem:
When I attempt to update kdesdk-devel from development, I get a message that
kdesdk-devel requires kdelibs-devel 3.4.0 ...
but kdelibs-devel-3.4.0-5 is installed.
BTW, if I rpm -e kdesdk-devel, I can then upgrade kdesdk.
OK, for some strange reason, I can now (4/22) install kdesdk-devel and
kdelibs-devel has not changed. I have no idea what this was all about.
