Title:
  tests fail in fedora 18 due a requirements problem

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  In a fresh installation of Fedora 18, when trying to run the tests
  with tox a dependencies problems in python packages makes them fail.

  The problem lies on pip's inability to process properly recursive
  requirements and deciding that pyparsing's version from the system
  (1.5.6) is fine while cliff (a python-quantumclient's requirement)
  needs at least 1.5.7.

  In pip's issue tracker (See https://github.com/pypa/pip/issues/988)
  they state that the best solution is to set in the main project the
  min/max version needed to prevent such problem.

  
  nova $ tox -e py27

  [...]
