I had hoped, since Tk is the default, expected, distributed-with-python
GUI framework (so says the python wiki) that it would "just work." On
the contrary, it appears that to make it work, I will have to install
Xcode, and figure out how to do an install of this package. And there
are several unknowns in that install, for OS X, beginning with, where in
/Library to put it, or if not in /Library, where? Wherever, I also have
to edit my .login to set PYTHONPATH appropriately so it can be found.
It seems to me this all amounts to quite a steep barrier for someone to
climb, just in order to try out the supposed default GUI.
I believe that the system build of Python 2.6 on Snow Leopard (the one
installed by Apple) is linked against Tk 8.5, which includes the ttk
widgets. You'd still need to install the Python ttk wrapper module from
http://code.google.com/p/python-ttk/, but that's easier than building
the Tile module from scratch. Just download the code, and run "sudo
/usr/bin/python setup.py install" and you should be in business.
To me, the really puzzling question is, since this has been the case for
several years (based on the history of the same error being encountered
repeatedly), why is the very latest Python apparently being distributed
with tkinter 8.4 but without tile?
The maintainers of the Mac build of Python from Python.org (not the same
as the system install of Python included by Apple) decided to keep their
build of Python linked to 8.4 for backward compatibility--that build of
Python has to support several versions of OS X. While they do distribute
Tkinter, they don't include the Tcl/Tk libraries that Tkinter depends
on--those are installed by Apple. Apple's installation of Tcl/Tk 8.4
doesn't include Tile for whatever reason, hence, Python's ttk module
won't work.
