title: ipython complaining about readline
body: <p>When I install ipython on my osx and run it, I get the following warning: </p>
  
  <pre><code> /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
   site-packages/IPython/utils/rlineimpl.py:96:
   RuntimeWarning: Leopard libedit detected - readline will not be wel
   behaved including some crashes on tab completion, and incorrect
   history navigation. It is highly recommended that you install
   readline, which is easy_installable with: 'easy_install readline'
  </code></pre>
  
  <p>I have have installed readline, and do not use the system python that was originally installed in <code>/Library/Frameworks/Python.framework/Versions/2.7/bin/python$</code>. The <code>/usr/bin/python</code> points to version 2.7 as shown below</p>
  
  <pre><code>uname -a

  $sudo pip install readline ipython
  
  $ipython --version

  $which python

  <p>I have read the question in <a href="https://stackoverflow.com/questions/1017909/python-sys-path-modification-not-working">Python sys.path modification not working</a> - I added <code>/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/readline-6.2.1-py2.7.egg-info</code> to the  <code>/Library/Frameworks/Python.framework/Versions/2.7/bin/ipython</code> so that it now looks like this: <a href="http://pastebin.com/raw.php?i=dVnxufbS" rel="nofollow noreferrer">http://pastebin.com/raw.php?i=dVnxufbS</a></p>
  
  <p>but I cannot figure out why I am getting the following error:</p>
  
  <pre><code>File
  "/Library/Frameworks/Python.framework/Versions/2.7/bin/ipython",
  line 9
  sys.path.insert(0,"/Library/Frameworks/Python.framework/Versions/2.7/lib/
  python2.7/site-packages/readline-6.2.1-py2.7.egg-info")
  </code></pre>
  
  <p>I do not think the above path is an issue, and my goal is to get ipython to working without complaining about readline even though it is installed and imports correctly.</p>
