I tried issuing the sudo port install command on the wiki page.

After some time running it failed with:

To fully complete your installation and make python 2.5 the default, please run

        sudo port install python_select
        sudo python_select python25

Which is singularly uninformative to me. It looks like I am not going
to be able to do any haskell programming next week when I am away with
only a macbook.
