title: toward iPython: easy_install can't find my Python(s) on Mac OS 10.5.8
body: <p>Installed setuptools-0.6c11-py2.7.egg on my Mac OS 10.5.8 but then </p>
  
  <pre><code>sudo easy_install readline ipython
  </code></pre>
  
  <p>yields a possible script problem?</p>
  
  <pre><code>Processing readline-6.2.0.tar.gz
  Running readline-6.2.0/setup.py -q bdist_egg --dist-dir /tmp/easy_install-N_JiZD/readline-  6.2.0/egg-dist-tmp-9IRgCS
  No eggs found in /tmp/easy_install-N_JiZD/readline-6.2.0/egg-dist-tmp-9IRgCS (setup script problem?)
  </code></pre>
  
  <p>and easy_install can't find my Python(s)</p>
  
  <pre><code>ERROR: 'IPython requires Python Version 2.6 or above.' 
  Exiting.
  error: Setup script exited with 1
  </code></pre>
  
  <p>however I just installed 2.7 and my active version is 3.0.1</p>
  
  <pre><code>$ ls /Library/Frameworks/Python.framework/Versions/
  2.7 3.0 Current
  </code></pre>
  
  <p>based on tips I found here, I tried installing setuptools directly into .../2.7/bin/ but all I got was a lecture from easy_install that </p>
  
  <pre><code>setuptools 0.6c11 is already the active version in easy-install.pth
  </code></pre>
  
  <p>another tip I saw here was to run</p>
  
  <pre><code>$ python2.7 setup.py install               
  /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory
  </code></pre>
  
  <p>That result is troubling.  How can I help easy_install find my stuff?  Have I done something goofy?</p>
