Programs depending on python or perl often need some specific python
libraries that apple does not provide (for example things like
py-scientific or p5-mailtools). It is not in macports' culture to
install things outside of /opt/local (or /Applications/Macports), so
installing these libs require a special libdir that your perl should
get. It is easier to count on a fresh install of python to find its own
libs than on the user to properly configure apple's python to find libs
in /opt/local.

Plus apple provided python is version 2.3. Macports provide python2.4 or
2.5 (maybe even python3k) so you have a better more recent with bug
fixes implementation and will be less likely to encounter and be enable
to correct bugs in that distribution (apple has long provided a buggy
ruby while macports' one was working well enough)

However, some programs do not require you to install python and work
well with apple's one (rubber for example, but I should correct its
portfile a little so that it is able to install with python >2.3).
