I installed zimbra on centos 4.2 64bit.
Antispam, antivirus, logger and snmp are stopped and if i try to start the service I receive the following error

ERROR: MISSING REQUIRED BASIC MODULES:
Time::HiRes
Unix::Syslog
Compress::Zlib
BEGIN failed--compilation aborted at /opt/zimbra/amavisd/sbin/amavisd line 148.

I have installed all libraries (zlib included)but if I run the command again, the same error still occurs.

I have tried to export mi PERLLIB

su - zimbra
export PERLLIB=''............. (path obtained with command "perl -V")
but if I run the command again, the same error still occurs.

any idea?
