I've gone ahead and built zimbra from the sources and installed it on my kubuntu/debian system. Unfortunately it's not working and I don't know nearly enough to understand why. The installation appeared to finish ok except that the user zimbra wasn't known to the system. After adding the user and group zimbra and changing all of the files and directories under /opt/zimbra to be owned by zimbra, the servers still won't start up. Running

su - zimbra -c bin/zmcontrol startup

produces the output:

Calling startup (localhost.localdomain)

perl bin/zmmon &

but then calling

su - zimbra -c bin/zmcontrol status

produces only

Calling GetServiceInfoRequest (localhost.localdomain)

Any ideas on what to do next?
