ipython complaining about readline

Question

When I install ipython on my osx and run it, I get the following warning:

 /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
 site-packages/I         


        

Answer 1

Additional note to future readers of this answer.

In my case -- running a MacPorts installation of IPython -- there were several versions of easy_install in /opt/local/bin/, but no non-versioned symlink pointing to the most current. Performing easy_install-2.7 -a readline worked.
