on a sles9 with sp2, the installation hangs on

Setting defaults...

That's it.

No ports ex. ssh is open, postfix, openldap and cyrus are down.

Seems, that it hangs with the script zmsetup.pl (shown in a "ps -ef").

Any ideas? How can i see, in which step the installation hangs?
Here the two logs of my server:

COMMAND: zmlocalconfig -s | sed -e "s/ = \(.*\)/=\'\1\'/" > /opt/zimbra/.saveconfig/config.save
-su: line 1: zmlocalconfig: command not found
COMMAND: zmcontrol shutdown
-su: line 1: zmcontrol: command not found
