After a linux install attempting to run results in this error when launching from shell:

Couldn't load XPCOM.

Here's the log entries:

[xx@sparky log]$ cat zdesktop.err
Zimbra server process is running as uid=500 euid=500 gid=500 egid=500
[xx@sparky log]$ cat zdesktop.out
0 INFO [main] log - Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog
1170 INFO [main] log - jetty-6.1.5
1903 INFO [main] log - No Transaction manager found - if your webapp requires one, please configure one.

Any ideas? This is a fedora 9 x86_64 install.
