Open Stack

Hello,
   I write a module to extend openstack. When install by python setup.py develop, it always blame this
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'pbr'
  warnings.warn(msg)

Creating /usr/local/lib/python2.7/dist-packages/UNKNOWN.egg-link (link to .)
Adding UNKNOWN 0.0.0 to easy-install.pth file


Installed /home/vagrant/rainflow
Processing dependencies for UNKNOWN==0.0.0
Finished processing dependencies for UNKNOWN==0.0.0






I do not know why the egg is UNKNOWN, and why the pbr option is unknown? i write the name in setup.cfg,
[metadata]
name = rainflow


the setup.py is 
root at test:/home/vagrant/rainflow# cat setup.py
#!/usr/bin/env python
import setuptools


setuptools.setup(
    setup_requires=['pbr'],
    pbr=True)




root at test:/home/vagrant/rainflow# pip list | grep setup
setuptools (7.0)
root at test:/home/vagrant/rainflow# pip list | grep pip
pip (1.5.6)


Did some one met similar problems? Thanks.....
