This error is already reported here:

http://trac.macports.org/ticket/22593

Recently, py26-pyobjc2 was replaced by py26-pyobjc and py25-pyobjc2 was replaced by py25-pyobjc. Maybe the same change needs to be made to py-pyobjc2 to merge it into py-pyobjc.

As far as I know, Python in MacPorts should generally work. Of course individual ports may be broken, for which tickets should be filed.


And as Joshua said, you might not want to be using the Python 2.4 versions of these ports; you may instead want to use the Python 2.6 versions of these ports, e.g. py26-pyobjc.
