Parsing Error happens when i do ceilometer test with "tox -e pep8".error message as below:stack@stack-perf:~/jenkins/workspace/gate-ceilometer-python27-pep8/distro/python27-10.239.47.56/ceilometer$ /home/stack/jenkins/workspace/gate-ceilometer-python27-pep8/distro/python27-10.239.47.56/ceilometer/.tox/pep8/bin/pip install /home/stack/jenkins/workspace/gate-ceilometer-python27-pep8/distro/python27-10.239.47.56/ceilometer/.tox/dist/ceilometer-2013.2.a175.gae9ccbd.zip -U --no-deps
