Bug 1019672 Add steps: pip, setup.py and running unit tests.

@bitgeeky r? If everything looks ok to you, we can run it by Bob.
I tried running through the instructions from scratch, to verify if they work and to check on that `setup.py` requirement, and I found that I get an error when trying to run the above command. I am on OS X 10.8.5. I know I was able to get this installed in the past (as I have it all running locally now), but this concerns me as I imagine others might run into the same issue.  The message from pip looks like this:

```

Is this something you can look into, @mjzffr?
