'upgrade command line error()' when upgrading NVFR to 4.1 (4045105)

Symptoms:
When trying to upgrade NVFR to 4.1 the upgrade fails with 'upgrade command line error()'.

Also, there was no mention of any upgrade activity in the /var/NVFR/ director,
/var/NVRDP is not present on the system

To trace the upgrade details,use the following command changing the directory 'root' with the directory where file upgrade-411.zip was saved. sh -x will give not only the output but also the command that generated the output.

sh -x /usr/nvfr/bin/do_upgrade.sh -q -f /root/upgrade-411.zip

it returns that there are failed dependencies:
warning: /tmp/dms_runtime_addon/openldap-servers-2.3.27-8.el5_1.3.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

bakbone-nvfr-4.1.1.38572.20100507-1 is not installed. Upgrade terminated.

This issue resulted on needing to install the ssl package that provides mod_ssl,

Installing the ssl package allowed the the upgrade succeeded.
