Just a reminder that you should *not* depend on the Apple-supplied Tk 
8.5 in OS X 10.6.  That was the first release of Cocoa Tk and it has 
proven to be almost unusable, at least with IDLE and some other 
Tkinter-based apps.  Install a newer Tcl/Tk 8.5.x, like from ActiveTcl, 
and use a python that links with it, like from the python.org 
installers. The ActiveTcl installer also installs "teacup" which allows 
you to easily install additional Tcl packages.
