Aqua Tcl/Tk, not X11 Tcl/Tk.

Because it does not play well with R.app.  Also, it is only version 8.4.7 
on my Mac (10.5.6) which is quite old and rather buggy, and Simon's build 
is 8.5.5 (I think).  8.4.x and 8.5.x are incompatible at binary level.

If you only use command-line R, the ActiveTcl version of Tcl/Tk version 
8.5.x works pretty well.
