Comment 4 for bug 706683

I am not seeing this sphinx problem after the pip-requires addition ... i can `run_test.sh -f` on both glance from glance/trunk (revno 50) and nova/trunk (rev 604) without issue ... however if this is a problem elsewhere, it might be prudent include the run_command(['tools/with_venv.sh', 'pip', 'install', '-E', venv, 'sphinx'] but probably not the argvparse as it doesn't error out
