>Description:
The file PREFIX/lib/python2.5/site-packages/easy-install.pth which tells Python what egg files to look in for libraries installed with the Easy Install system is not maintained across upgrading the devel/py-setuptools port. This means that after an upgrade importing libraries which where installed with the Easy Install system will fail.
>How-To-Repeat:
Upgrade devel/py-setuptools.
Run Python and try to import a library installed with Easy Install (for example devel/py-pytz):
    [douglas at slowhand:~]$ python
    Python 2.5.1 (r251:54863, Nov 10 2007, 23:43:31)
    [GCC 3.4.6 [FreeBSD] 20060305] on freebsd6
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import pytz
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ImportError: No module named pytz
    >>>
>Fix:
The current workaround is to reinstall all of the ports which use the Easy Install system.
