Hopefully, we're going to be making a dent in that in the next version of Ubuntu. This is still a big mess in Gentoo and MacPorts, though. MacPorts hasn't done anything about ceating a transition infrastructure AFAICT. What kind of "transition infrastructure" would it need? It's definitely not going to replace the Apple-provided Python out of the box, so setting python to a python3 is not going to happen.

It doesn't define a python3, so maybe that? Is there a document somewhere on what kind of things distros need for a transition plan?

Gentoo has its "eselect python set VERSION" stuff, but it's very dangerous to set to a Python 3 version, as many things go permanently wonky once you do. (So far I've been able to work around problems this creates, but it's not much fun.) Macports provide port select which I believe has the same function (you need to install the python_select for it to be configured for the Python group), the syntax is port select --set python $VERSION:

python --version Python 2.6.1 sudo port select --set python python32 Selecting 'python32' for 'python' succeeded. 'python32' is now active. python --version Python 3.2.2
