This support is usually provided by libreadline, and it is possible 
that the version of python compiled for your system did not include 
that functionality.

You can determine whether python has libreadline support by doing 
(something like) the following (I'm using 'bash' as my shell):

$ type python
$ ldd /usr/local/bin/python
...long list of libraries...

If readline is not in the list, python on your doesn't handle arrow 
keys or other "emacs-like" keystrokes.
