Just a quick note for others like me:
Zimbra: Multi-Node Zimbra Installation
OS: CentOS release 5 (Final)

Was running 5.0 RC2
Was upgrading to 5.0 GA
Received same errors as this thread
prov> prov> 5 is only avaliable with the XS version at /opt/zimbra/zimbramon/lib/IO/Socket/SSL.pm line 30
BEGIN failed--compilation aborted at /opt/zimbra/zimbramon/lib/IO/Socket/SSL.pm line 30, <DBCONFIG> line 17.
Compilation failed in require at /opt/zimbra/zimbramon/lib/Net/LDAP.pm line 970, <DBCONFIG> line 17.

So I tried a few things..

I set the Perl Paths as referenced by a few threads in my root .bashrc file
PERLLIB=/opt/zimbra/zimbramon/lib/x86_64-linux-thread-multi:/opt/zimbra/zimbramon/lib:/opt/zimbra/zimbramon/lib/i386-linux-thread-multi:/opt/zimbra/zimbramon/lib/i486-linux-gnu-thread-multi:/opt/zimbra/zimbramon/lib/i586-linux-thread-multi:/opt/zimbra/zimbramon/lib/darwin-thread-multi-2level
export PERLLIB

PERL5LIB=$PERLLIB
export PERL5LIB
(logged out and back in)

Then I ran a yum upgrade perl

Then the install worked successfully.

Hope this helps others
