FC2: KDE won't start up due to shared library error

[bdw at briandwright.com]

When I try to start KDE on FC2, I get the following error in my
~/.xsession-error file:

startkde: Starting up...
ksplash: error while loading shared libraries:
/usr/lib/qt-3.3/lib/libqt-mt.so.3: undefined symbol:
XkbSetPerClientControls
kdeinit: error while loading shared libraries:
/usr/lib/qt-3.3/lib/libqt-mt.so.3: undefined symbol:
XkbSetPerClientControls
startkde: Could not start kdeinit. Check your installation.
xmessage: error while loading shared libraries:
/usr/X11R6/lib/libXaw.so.7: undefined symbol: XmuCvtGravityToString
Warning: connect() failed: : No such file or directory
ksmserver: error while loading shared libraries:
/usr/lib/qt-3.3/lib/libqt-mt.so.3: undefined symbol:

startkde: Shutting down...
Warning: connect() failed: : No such file or directory
Error: Can't contact kdeinit!
startkde: Running shutdown scripts...
startkde: Done.

The right packages were installed, I just can't figure out why the there's
an undefined symbol error.
