Fresh install of Ubuntu Server 7.10 and Zimbra 4.5.3 (first time installing so I just followed a how to on howtoforge). I keep getting the same errors when I do 'zmcontrol status':

Host server1.mydomain.local
antispam Running
antivirus Running
ldap Running
logger Running
mailbox Running
mta Running
snmp Running
spell Stopped
zmapachectl is not running

And when I do 'zmcontrol start':

Host server1.mydomain.local
Starting logger...FAILED

Starting mailbox...Done.
Starting antispam...Done.
Starting antivirus...Done.
Starting snmp...FAILED

Starting spell...FAILED
/opt/zimbra/httpd-2.0.54/bin/httpd: error while loading shared libraries: libdb-4.3.so: cannot open shared object file: No such file or directory

Starting mta...Done.

I've been searching and cannot find a solution. Anyone have any ideas?
