[Zope] Upgrade to 2.7.2 results in all content unavailable - SOLUTION!

[Thomas Bennett]

So was this RHEL machine customized to update ZOPE with YUM or Up2date or is 
this a default.  I have been using Fedora and CentOS (both built from redhat 
dist.) for some time now and haven't seen this issue.  This would be nice to 
know seeing that I am currently moving all my linux servers to RHEL5.

Thanks

Thomas
