I am trying to upgrade Zimbra from 4.5.8 to 5.0.2 and kept getting the following installation error:

Code:
Starting logger mysql
This appears to be 4.5.8_GA
Redolog Version: 1.21 New Redolog Version: 1.21
Schema upgrade required
Running /opt/zimbra/libexec/scripts/migrate20070306-Pop3MessageUid.pl
perl: symbol lookup error: /opt/zimbra/zimbramon/lib/i386-linux-thread-multi/auto/DBI/DBI.so: undefined symbol: Perl_Tstack_sp_ptr
Script failed with code 32512:  - exiting

I search the forums and saw people were getting a similar error and the idea was to setup a SplitDNS which I did and that didn't help.
