I agree with Barry here -- I would even go further and say that
the Python used by system apps (i.e., apps that the OS depends on)
should be separate and should not be on the default PATH (so the user
can't use it accidentally), and no non-system apps should use the
system Python unless specifically installed by the user or sysadmin
into the system Python's area.

I used to always set up my own Python[s] in /usr/local
and put that first in my PATH, but I have gotten lazy lately, and
sometimes it will bite me. ;)
