Comment (by kencu):

 We didn't know that the macports builds were unaffected until the details
 about flat_namespace came forth.

 Only once it was known that flat_namespace was the key piece of the
 puzzle, and also knowing that macports doesn't use flat_namespace due to
 -- well, essentially lucky reasons, basically -- we realized macports was
 unaffected and we had dodged this bullet.
