title: Installing pip3 with a virtualenv
body: <p>I am trying to clean up a few things now that I have Mavericks. I used Homebrew to install python 2.7 and 3.3. I also have their respective pips. Now I want to have a sane virtualenv setup. </p>
  
  <p>I see from <a href="https://stackoverflow.com/questions/12566064/virtualenv-with-python2-and-python3-via-homebrew">virtualenv with python2 and python3 via Homebrew</a> that I can specify which version of python a newly-created virtualenv will use. What is the best (i.e., easiest to use/remember) way to make sure that a virtualenv using Python 3.3 uses pip3?</p>
  
  <p>ETA: I've not had to use 3.3 before, so this is my first experience trying to maintain different versions. Sorry if this has an obvious answer.</p>
