BTW, for posterity, it's not just a matter of using the python.org or
Enthought binaries; you also have to do:

$ sudo easy_install readline

as described here: http://ipython.scipy.org/moin/InstallationOSXLeopard

Though I'm not totally sure why, as the python.org binaries, at least,
are advertised to "include both bsddb and readline"
