pip install SchemaObject breaks; ez_setup not included in distribution

Probably just need to include ez_setup in MANIFEST.in, but here's the output:

    [prompt]$ pip install SchemaObject
    Downloading/unpacking SchemaObject
      Running setup.py egg_info for package SchemaObject
        Traceback (most recent call last):

          File "/path/to/virtualenv/build/SchemaObject/setup.py", line 2, in <module>
            import ez_setup
        ImportError: No module named ez_setup
        Complete output from command python setup.py egg_info:
