I don't know how it is finding it.  But when GRASS starts, it opens a terminal and reports some things.  One thing is the Macports versions of python.  But then if I go into that same terminal and type python, I see the version that is selected with python_select.
It is also strange that one of the binaries is finding the 2.5 while the other is finding 2.6.  I have also been in touch with the guys who built these binaries, and they are being helpful to try to track it down.  But the initial response was that there is just a conflict between what their wxPython sees as the Python is it supposed to use and what your systems sees as the proper Python to use.

But it must be that python_select is missing some way to "hide" the other versions.  Because they are being found.

I have not because it is somewhat old.  (6.3, while I am using 6.4).
