I just tried it.  Needs a bit of work.

It should accept yes (enable).  This would use the default framework  
path, much like --with-tcltk or other options that don't add -L/usr/ 
lib.  So, --with-tcltk-framework would set:

TCLINCDIR = -I/{found location}/Tcl.framework/Headers
TKINCDIR = -I/{found location}/Tk.framework/Headers -I/{found  
location}/Tk.framework/PrivateHeaders
TCLTKLIBPATH =
TCLTKLIBS = -framework Tcl -framework Tk

Of course, some extra detection logic is needed to check for the  
frameworks in /Library/Frameworks, then /System/Library/Frameworks.

If a path is used, then the -F flag is added to TCLTKLIBPATH.


When I used a path with the option, the framework flags didn't get  
inserted into platform.make.  TCLTKLIBS is empty.


Also, the framework option should be rejected if opengl is not aqua.
