title: Unable to set iPython to use 2.6.1 Python
body: <p>I have installed the newest iPython in Mac. However, it uses the Python verion 2.5.1.</p>
  
  <p>I installed the Python 2.6.1 by MacPython package at <a href="http://www.python.org/download/" rel="nofollow noreferrer">here</a>. </p>
  
  <p><strong>How can I make my iPython to use Python 2.6.1?</strong></p>
  
  <p>I am not sure where the MacPython package exactly installed the newest Python.
  The <strong>newest Python should somehow put the PATH</strong> so that iPyhon can use it.  </p>
  
  <p><strong>[edit]</strong> after the first answer</p>
  
  <p>I run the following command</p>
  
  <pre><code>$ln -s python python2.6
  </code></pre>
  
  <p>I cannot open python2.6 by </p>
  
  <pre><code>python
  </code></pre>
