How do I uninstall python from OSX Leopard so that I can use the MacPorts version?

Answer 1

Unfortunately I don’t know how port commnad works (I guess it comes from MacPorts) but you should use Python to maintain Python packages (which is encouraged eg. by homebrew). You can try pip:

sudo pip install scikits.learn

In OS X Lion default version of Python is 2.7, if you want to use 2.6 you have to:

sudo python2.6 pip install scikits.learn

(Python keeps separate packages for every version)

You can browse all packages available via pip (or easy_install) using pypi or search it with

pip searh foo

If you are afraid of cluttering you system please give a try virtualenvwrapper.
