How do I resolve this issue on Centos Linux > 5.5? Thank you. First, the current release is 5.6, so 5.5 is unsupported. More than likely, the QT package on CentOS is not new enough to be compatible with a Fedora 14 package. Either run Fedora, wait for CentOS-6 which has a better chance of working, or try an evaluation copy of RHEL6, or give Scientific Linux 6 a test drive in the interim. Phil
