Upgrade of Zend Server to 5.6, now versions don't match

[bradummer]

We're running Red Hat Enterprise Linux Server release 5.6 (Tikanga) and have Zend Server installed. Prior to a recent upgrade Zend Server was 5.0.4 and PHP 5.2.17. We wanted to upgrade to the most recent release (Zend Server 5.6.0 and PHP 5.3) so I followed the instructions and ran:

yum update \*zend\*

I went through the process and everything seemed to have upgraded successfully. Checking the version from the command line shows that it was upgraded:

[root]$ /usr/local/zend/bin/zendctl.sh version
Zend Server version: 5.6.0

However when I go into the Zend Server web control panel, it says my version is still 5.0.4 and PHP is still 5.2.17. More strangely, if I go to Administration > Updates in the Zend Server web control panel it says that my Installed Version is 5.6.0-343 but my Available Version is 5.0.4-41. I've tried restarting Zend Server, restarting PHP (using the control panel), and restarting Apache. Nothing seems to rectify the situation. When I run the yum update again it says No Packages marked for Update.

Everything seems to be running OK, but I just want to figure out how to finish the upgrade process. Any ideas?
