[Python-projects] Problems with latest astng or common or with setuptools/easy_install?

[skip at pobox.com]

I saw the announcement about astng 0.17.4 so I easy_install'd it and also
made sure my logilab-common and pylint pakages were up-to-date.  These eggs
were listed in easy-install.pth:

    ./pylint-0.15.2-py2.7.egg
    ./logilab_astng-0.17.4-py2.7.egg
    ./logilab_common-0.36.1-py2.7.egg

When I run pytest it complains:

    Traceback (most recent call last):
      File "/Users/skip/local/bin/pytest", line 5, in <module>
        pkg_resources.run_script('logilab-common==0.36.1', 'pytest')
