Pythoscope packaging modules which interfere with system modules

[Sarah Mount]

Pythoscope packages a bunch of modules like lib2to3. I have Pythoscope installed, system-wide, on vanilla Ubuntu Pangolin and I get this:

$ python
Python 2.7.3 (default, Aug 1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import lib2to3
>>> lib2to3.__file__
'/usr/local/lib/python2.7/dist-packages/pythoscope-0.4.3-py2.7.egg/lib2to3/__init__.pyc'
>>>

In the Django project, we avoid these problems for the libraries that we do bundle by deferring to system-level packages, and only using our bundled versions if there aren't other copies avaliable. For example, here's how we do it with the unittest library:
