This new approach seems to work well. I've tested it not just with the
basic demo but with a different script that incorporates a Tk-specific
extension with a Python wrapper (Tile). Thank you.

My only reason for wanting to use a universal build of Tcl/Tk is to
avoid things breaking if the application runs on a later version of OS X
with a later version of Tcl/Tk installed in /System. Can the tkinter
module accommodate a later 8.4.x build of Tcl/Tk without breaking?
