I don't use python. But I believe the idea was that there are
significant differences between python 2.4 and 2.5, and that there is
some software that works with 2.4 but not 2.5, some that works with
2.5 but not 2.4, and some that works with both 2.4 and 2.5 but with
significant changes in how that's done. So the decision was to have
separate portfiles. I have no information on how python 3.0 fits into
the picture now. Perhaps someone who uses python can comment.
