Hi,

I've committed the following mega-patch which does two things. First, 
trivially, it updates the sources for use with Itcl 3.3. Second, and 
more important, I've added machinery to use the system-supplied versions 
of Tcl and Tk.

I'm on my way to eradicating our need for having our own versions of 
tcl, tk, and itcl et al.

If there are any problems, please send a note to this list.

New itcl3.3 and updates to insight coming shortly.

Keith
