How do the .dmg files work? Are these binary installers into the system Python? I would expect that these wouldn't work with a manually installed Python from python.org, but I have no experience with them.
Tom, I have had very good luck with the brew Python 2.7 installer, which will give you a /usr/local Python base install and easy_install. Brew can also install readline correctly for you. https://github.com/mxcl/homebrew/wiki/Homebrew-and-Python If you want an all-in-one solution, you can also grab either the free EPD distribution or another of the "all-in-one" packs.
