When I try to run coverage, I get error:

# coverage
Traceback (most recent call last):
  File "/usr/bin/coverage", line 5, in <module>
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resources

When I install python-setuptools, coverage starts to work:

# yum install python-setuptools
