The way the GRASS-Mac startup is configured, it looks for python in this order:

  what's set in GRASS_PYTHON (full path to pythonw, needed for wxpython GUI)

  what is found in the PATH (/opt is probably in your PATH)

  the python.org Python (/Library/Frameworks)

  the system python

It checks each for the python version needed, but not the architecture.  the error you are getting is probably because GRASS needs to run python 32bit because of Wxpython limitations, but the /opt python is 64bit only.  That's odd that macports does that since you need wxpython 3 to be able to run 64bit.  But GRASS should have its own wxpython bundled, and it's best to use the python it was compiled for (system python as Michael said).

I don't know how to best set the environment to use the system python. It is best to ask the list if someone has done this (copied here). OS X is a version of Unix, which is similar but not identical to Linux. Many of the configuration files for setting environmental variables are similar between OS X and Linux, but they can vary sometimes.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarrely inexplicable.  There is another theory which states that this has already happened.
