I'm trying to install M2 on a fresh Red Hat box. Everything goes well until the installation of zimbra-store, which fails, leaving these messages in the log:

Preparing packages for installation...
cat: /opt/zimbra/zimbramon/zimbramail.cf: No such file or directory
-bash: jar: command not found
-bash: jar: command not found
error: %post(zimbra-store-3.0.0_M2_740.RHEL4-20051114171614.i386) scriptlet failed, exit status 127
I couldn't find any other references to this error message in the forums. Thanks for any suggestions.
