Success!  
Just doing this in my .profile:
 export GRASS_PYTHON=/usr/bin/pythonw2.6

solved the problem.  So I think that the issue is that macports just makes links for "python" and "pythonw" while you were actually searching for "pythonw2.6".

But, Micheal, this fix doesn't work for your build.  I think that reason is that your version of MacOS/grass.sh in 6.4 (I haven't checked any others) actually contains this:
pyver_want="2.5"

While William's contains this:
pyver_want="2.6"

So, your version is searching for, and finding, pythonw2.5, which is the macports only version.  If macports wasn't installed, then it would move on to the 2.6 version, since it can't find 2.5.  

Thanks for all the help from both of you....
Although I have not yet tried to georectify with wxpython, which was the whole point of this exercise initially.
