commands. If you update your editions of these (install Python3000, Ruby 1.9),
you may end up with "unexpected" behavior.
For example, an install of Python 3000 via Darwinports placed 'python' in my
'/opt/local/bin'. This took precedence over the system standard
'/usr/bin/python'. I tripped over this error when trying to use the LaTeX
Bundle's "Typeset and View" command. While the pop-up said "Typesetting
$Filename...," nothing ever returned. Only after debugging did I see that the
command was calling a Python script that, it turns out, was using a
non-backwards compatible interpreter.
Just make very sure you know what your path is and that you know that you're
using safe interpreters.
