The author states Lion’s default Python install is a healthy Python 2.7.1.
I have personally had an unreasonable amount of trouble installing and using Python libraries and environments on Snow Leopard. I think right now I have at least 3 different versions of Python installed, each with various and disparate libraries. Has this been addressed in Lion? Getting Numpy, Scipy, etc to work is a chore; especially when comparing it to the Linux experience.
I used to have trouble getting numpy and scipy installed - until I started using homebrew. It blows MacPorts out of the water. Just make sure your architecture is set correctly as Jesse outlines in this blog post, otherwise you'll run into problems building the various C components with gcc.
What he said; use homebrew - judicious use of homebrew and virtualenv will save you lots of pain. I never install framework builds from python.org - I don't like installing things into /Library or ~/Library
