The problem is that you are using a non-Mesa GL library (see the undefined symbol message), probably NVidia's closed-source drivers. We do not support this configuration. If you get the Qt SRPM and recompile (rpm --rebuild qt-2.1.1-6.src.rpm), you should get a Qt binary that will fix the problem for you (but this binary will break for Mesa users).
