>Description:
Koobs and I have discussed this, but I'm recording it here so that it can be tracked.  

The py-virtualenv port is missing a run dependency on py-setuptools.  Thus, you're able to install py-virtualenv and when trying to create a virtualenv, you're met with this error:


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

If you've installed via ports, you won't run into this issue unless you remove the py-setuptools port (because it is installed as a build dep).  However, with packages on a clean machine, installing py-virtualenv will only require python which is insufficient.
>How-To-Repeat:
Build a py-virtualenv package, install it, then execute /usr/local/bin/virtualenv foo.
