[AstroPy] Enthought Canopy vs. another distribution for Mac?

I agree, MacPorts is the way to go. Enthought's 'Free' distribution is crippled; it's 32-bit, which limits speed and array sizes on modern 64-bit machines. MacPorts provides not just Python itself, but hundreds of Python packages, including many that are related to astronomy and other science disciplines.

It's very similar to the apt or yum system used on linux boxes.  It leaves your system python untouched, but lets you install pretty much any free python package out there and allows you to keep everything up to date. (It also works with plenty of other free and astronomically useful software e.g. gcc, gfortran ,editors).  It also provides simple instruction with installation for how to manage which python is used by default.   I dabbled in Enthought and the system python, but I've found Macports to more reliably reproduce the pain-free python experience from linux.
