Somehow you have Python2.7 files already present in /Application/MacPorts/Python2.7.

I'm mostly curious how that occurred, which is likely what Russell hinted: MacPorts was only partially removed at some point.

But yes, I'd recommend letting MacPorts take over its own directory again via forcing activation.
