title: Trouble setting Python version in Sublime Text2
body: <p>I'm having trouble setting the build environment in Sublime Text2.
  I'm using Macports for Python and package installation.</p>
  
  <p>My python.sublime-build file looks like this:</p>
  
  <pre><code>{
      "cmd": ["python", "-u", "$file"],
      "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
      "selector": "source.python"
  }
  </code></pre>
  
  <p>I think (from searching) that I need to modify the "cmd" line to point to the Macports version. Anyone done this successfully?</p>
  
  <p>From Terminal, everything builds/runs fine, it's only Sublime Text2's build that's grabbing the system version still.</p>
  
  <p>Additional info:</p>
  
  <pre><code>which python
  /opt/local/bin/python
  </code></pre>
  
  <p>Thanks for any help.</p>
