You'd have to build your own TclTk frameworks, since the ActiveTcl is  
32bit only.  I'll have to try that - my last notes (last July) say  
that 64bit Aqua wasn't working yet, only 64bit X11.

I suppose you may get a little speed, but I thought 64bits was more  
about volume, or more accessible memory.  As I understand it, the  
32bit mode on 64bit Intel processors isn't really much slower, if at  
all, than 64bit.  This is certainly true for PPC processors, those  
have been 64bit from the start and 32bit 'mode', used in OSX before  
Leopard, is designed to be just as fast.
