Getting Oauth2 to work with Python on a Mac

I am ataking a coursera course in Data Science and having trouble getting the prelim check for the first assignment to run without errors.  Here are the details  any help is appreciated!
Using Mac OS 10.8.5
Which Python returns:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
Running the first assignment script after updating teh API calls results in this:
$ python twitterstream.py > output.txt
Traceback (most recent call last):
  File “twitterstream.py”, line 1, in <module>
    import oauth2 as oauth
ImportError: No module named oauth2

So I go back double check my oauth2 installation
$ pip install oauth2
Traceback (most recent call last):
  File “/usr/local/bin/pip”, line 5, in
    from pkg_resources import load_entry_point
  File “/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py”, line 2603, in
    working_set.require(__requires__)
  File “/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py”, line 666, in require
    needed = self.resolve(parse_requirements(requirements))
  File “/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py”, line 565, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: pip==1.5.2
So now I investigate PIP:
$ which pip
/usr/local/bin/pip

Not even sure what that means, but ...
