Install twisted in a virtual environment on OS X Mavericks

A recruiter suggested that I look at twisted before having an interview with a client.  Strangely enough, learning how to install twisted in a virtual environment on OS X Mavericks is not easy probably because some of twisted is installed in OS X anyway.  However, I was not using the system python.  I was using the python I installed with brew, so I kept getting this error message:

ImportError: No module named twisted

After poking around a little bit, I finally broke down and asked Stack Overflow:

First, I made a virtual environment called try_twisted, and then I installed twisted with pip:

(try_twisted)christohersmbp2:try_twisted christopherspears$ pip install twisted

Now twisted works:

(try_twisted)christohersmbp2:try_twisted christopherspears$ python
