As you may have discovered, by default the Python 2.7.x and 
3.2.x on OS X 10.6 and above will link with the readline compatibility 
layer supplied with BSD editline (libedit) shipped by Apple.  The 
Apple-suppled system Pythons also link with editline.  While it is 
possible to link with your own version of GNU readline, there is also a 
readline project listed on PyPI that supplies pre-compiled versions of 
the Python readline module linked with GNU readline.  I believe they are 
intended primarily for the system Pythons; I have not tried them myself 
with the versions.
