I had no idea the "10.4" fat binaries were compatible with 10.3.9! Wow!

There is one issue, however: my app is a Tkinter app and it needs to 
run under Intel and PPC Macs. Right now I enforce that by building 
everything PPC-only and having it run under emulation on Intel -- 
which works fine.

If/when a fat Aqua Tcl/Tk comes out that works with my app, I can try 
to make it all fat. But that could be awhile. I suspect the current 
ActiveState Tcl/Tk (8.4.13) is not fat, and even if it were -- Aqua 
Tcl/Tk 8.4.13 and 8.4.12 both have bugs (losing the mouse position) 
that are killers for my app (but 8.4.11 works fine).

I've been assuming that either all components need to be fat or else 
all need to be PPC-only to be safe on Intel. Perhaps that's too 
paranoid?

P.S. Python 2.4.1 isn't an issue for me. I use ActivState's PPC 
Python 2.4.3 at work.
