I traded emails with hughesjr, and he suggests that this is a 'safe' way to downgrade perl 5.8.8 to perl 5.8.5 using rpm --nodeps is as follows:

Just to be safe, stop anything you think might be related to perl including zimbra

Check your perl verison
#perl -v
This is perl, v5.8.8 built for i386-linux-thread-multi
#sudo rpm -e --nodeps perl-5.8.8-4.el4s1
(also uninstall perl-suid if you have it installed)
#sudo vi /etc/yum.repos.d/CentOS-Base.repo (add 'exclude=perl*' under [centosplus])
#sudo yum install perl (for me this also added perl-Filter through yum dependency checking)
#sudo reboot
#perl -v
This is perl, v5.8.5 built for i386-linux-thread-multi

After these steps, check if the directory or any code is left in /usr/lib/perl5/5.8.8/* That directory shouldn't exist, but if it does, then you had some perl stuff that depended on 5.8.8 in there that you should look into (reinstall for 5.8.5).

Hope this helps someone out!

Replying to myself. I downgraded perl 5.8.8 to 5.8.5 and it worked fine - upgraded 4.5.10 NE to 5.0.1 NE on CentOS 4.6. Everything is good on 5.0.1, no errors on install.
