title: Choose which version of python to use when installing with yum
body: <p>I have 3 versions of Python on my Linux VPS (CentOS). Version 2.6 is the system python. I want to install modules to python 2.7 but running the following command just installs to python 2.6. How do I specify python 2.7 in this command?</p>
  
  <pre><code>yum install python-devel
  </code></pre>
  
  <p>Thanks!</p>
