I've been unable to reproduce this using pip 1.5.4 on ubuntu trusty; but in my case, the elements were installed under/usr/local/share/diskimage-builder rather than /usr/share/diskimage-builder
I *have* been able to reproduce this with pip-1.0 on ubuntu-precise (although, again, /usr/local/share/diskimage-builder rather than /usr/share/diskimage-builder). I've also been able to reproduce with pip 1.3.1 on fedora19 - in this case, /usr/share/diskimage-builder.
