Philip Schaffner, Thank you for your reply. I guess we will have to wait until Centos 6 arrives to get a working QT. Did you see Nicolas Thierry-Mieg's response regarding yum install oprofile-gui. We were able to install oprofile-guii.i386 0:0.9.4-15.el5.centos and oprofile.i386 0.0.9.4.15.el.5.centos. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...
