AFAIK, on Unix-y systems Modules/Setup isn't normally used to configure 
the building of _tkinter anymore.  The relevant code is in Python's  Search there for "_tkinter" and "detect_tkinter".  You'll 
find a lot of platform-specific hacks but you should be able to 
substitute your own version of Tcl/Tk through the use of ./configure 
arguments, most likely by adding your Tcl/Tk directories to the 
INCLUDEDIR and LIBDIR variables; see the beginning of detect_modules()
