I need php 5.3 to support Joomla 1.7 and latest release of wordpress.
So here is my plan for Centos 5.6
yum remove the 5.1 packages taking note of what is removed along with the php packages.
yum install the equivalent php53 packages. My found the mcrypt package in epel.
Now that that repo is back in /etc/yum.repos.d I can install the mcrypt package and we'll see if that what was breaking squirrelmail.
If that fails I'll post my error message. Making this work will save me a ton of time.
Time that needs to be spent finding a new contract (remaining employed).
