[Tutor] Python 1.5.2 on iBook running Mac OS 9

[Corran Webster]

This is a question which perhaps belongs in the MacPython SIG - you will
certainly be able to find help there on technical mac-related issues like
this.

Unfortunately, in 1.5.2 the locations that modules are stored in were
changed, and in that change the location of _tkinter was omitted from the
standard path.

To make things work, you need to find _tkinter.ppc.slb (which is, I
believe, somewhere in the :Extensions:Imaging folder) and move it to
somewhere in your python search path (:Mac:Plugins is the usual location).

After you have done this, you will need to make sure that :Lib:lib-tk is in
your python path.  Run the "EditPythonPrefs" file and add the line

$(PYTHON):Lib:lib-tk

to the list if it is not already there.

This should get you back to the same amount of support for Tk as previous
versions of Python for the Mac.

Also, you will have to run Tkinter based scripts using the interpreter,
rather than the IDE.
