title: Install pandas v.0.13 (dev version) in Python 2.7
body: <p>How can I install pandas dev version in my Python 2.7 (and OS X 10.9 and pip 1.4.1 for your information).</p>
  
  <p>When I installed pandas using pip, the installed version is v.0.12 (latest stable version) for sure. However, when I cloned the repository from Github and installed it using <code>setup.py</code>, the installed version is also v.0.12. So is it feasible to install v.0.13 under my system, and if it is, how can I do?</p>
  
  <p>I don't want to use Scipy Superpack, which would install the dev version, since I like to install the dev version only on pandas, not on numpy, scipy, etc... as well.</p>
  
  <p>I also want to install it under my Python 3.3 if it's feasible, but would be glad to accept it only on Python 2.7.</p>
  
  <p>Thanks.</p>
