I'm a pretty much a newb to BSD and have not contributed to the ports
collection; apologies if I'm off track on the thread.

The Python source build has IIRC an altinstall flag that allows you to
have multiple versions on the machine.  I've got the Python from ports
(I believe it's 2.5) and Python 3.0 (installed from source with
altinstall) on my FreeBSD laptop.  I was surprised that a port for 2.6
was going to be available so soon (thanks).  I'm not sure if the
method I've laid out for 3.0 is considered good practice within a
FreeBSD context, but it's handy for having more than one version of
Python on a machine.

The advantage of doing the install with ports is that there is some
assurance as to the security and functionality of the software (it
will work under the FreeBSD OS).  If there is a dependence within the
port, even one just required to build the port or use its Makefile, as
a newb at least, I expect it to show up in the port's dependencies.

My 2 cents of a possibly relevant nature.
