[TxMt] Re: using python 3.0.1

[Andrei Maxim]

Christian,
I just took a closer look at the "Update Shell Profile.command" script that
you were supposed to run and I noticed that if you don't have
~/.bash_profile, ~/.bash_login or ~/.profile the script will create
~/.bash_profile.

In case you didn't know, "~/.bash_profile" is the file called
".bash_profile" (notice the leading dot) in your home directory (i.e.
"/Users/christian/" if you short username is christian).

If you open that file you should see at least these lines, probably at the
end of the file:

# Setting PATH for MacPython 3.0
# The orginal version is saved in .bash_login.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.0/bin:${PATH}"
export PATH

These lines will place the Python 3.0 executable files before the default
executable files and when you'll run "python -V" Bash will run the python
executable in the Python 3.0 folder because there's the first match. The
same thing happens when running "/usr/bin/env python".

You need to change the search order because most scripts are expecting
Python 2.x, not 3.0 (and probably the LaTeX bundle requires Python 2.x). So
you need to change the third line to:

PATH="${PATH}:/Library/Frameworks/Python.framework/Versions/3.0/bin"

What you're doing is changing the search order so Bash will run
/usr/bin/python first, which is version 2.5.1. You'll need to use
/usr/bin/env python3.0 in your scripts' shebang line to make sure your code
is running 3.0.

I hope this clears things up.
