I also notices that cinder-volume has a dependency on python-glanceclient as well - I had to install this first to get the above confirmation of the original error report.

@James : I have the same error.

To fix it, you need to modify default cinder.conf with "rootwrap_config = /etc/cinder/rootwrap.conf"

This bug was fixed in the package cinder - 2012.2~rc1~20120907.230-0ubuntu4
