Testing package set / solving RPM inter-dependencies...
There was a package dependency problem. The message was:
Unresolvable chain of dependencies:
XFree86-Xvfb-4.3.0-78.EL                 requires XFree86 = 4.3.0-78.EL
mozilla-chat-1.4.3-3.0.4                 requires mozilla = 37:1.4.3-3.0.4

The system is a RHEL 3 U4 trying to bring it up to date to U5 - it
panicked during up2date since then these dependencies issue showed up
and didn't find a way around it yet.
Any ideeas how to fix this problem? I've tried installing the packages
with the -i option still no go, nor --solvedeps=<deps> would work.
