As a sysadmin with a decent amount of LAMP and dependency-hell behind
me, I can only say that Jennifer's already covered what I would say,
and in much nicer words to boot.
But to reiterate:
1. Be careful and consistent where you get stuff; mixing CPAN downloads
with distribution-packaged Perl modules is asking for trouble.
2. Be careful what and when you upgrade, and plan for breakage.
3. Use a separate test server.
If you want to go the grumpy-professional-sysadmin route:
4. Document things well enough that you can rebuild your
server/environment from an OS install CD and your PHP source.
5. Get a spare box, set aside a couple days and actually DO #4.
6. Try migrating the app to Debian or Centos.
7. Don't let devs have root access.
