Ouch! I'm sorry, but these are wildly *dangerous* instructions. Please
disregard them. The author is reckless.

You can't undo the damage without reinstalling OS X, but there is a
good chance you will not run into the parts of OS X that depended on
the /System Python being unmolested. However, you do need to reinstall
the python.org Python framework again. Just don't mv it from where it
gets installed. Then the numpy-1.6.2-py2.7-python.org-macosx10.3.dmg
will recognize it.
