Something else in the snapshot is not working correct for me with a new install.
# sudo rm -rf /var/ossec
# sudo rm /etc/ossec-init.conf
# wget
http://www.ossec.net/files/snapshots/ossec-hids-091118.tar.gz
# tar xfvz ossec-hids-091118.tar.gz
# cd ossec-hids-091118
# sudo ./install.sh
[.....I select Server and just hit enter till i get back to prompt...]
# sudo /var/ossec/bin/ossec-control start
