Let's verify that then. I have the following RHCS related packages
installed:
ccs-1.0.7-0
rgmanager-1.9.54-1
cman-1.0.11-0
fence-1.32.25-1
cman-kernel-smp-2.6.9-45.8
dlm-kernel-smp-2.6.9-44.3
dlm-1.0.1-1

/etc/redhat-release contains:
Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Thanks,
Frederik
