unable to create OpenStack credentials

Hi,

I tried creating the nova credential zip file and it failed because the /usr/lib/pymodules/python2.6/nova/..//CA directory did not exist. And threw the below error. However, when I copied files from CA from source code directory (present case /home/shinys/openstack1/nova-2011.1/CA) to /usr/lib/pymodules/python2.6/nova/..//CA, it worked fine for me. Shouldn't this be an automated procedure? Well I tried the solution at https://answers.launchpad.net/nova/+question/134376, it didnt help.
