Hmm, it IS related.  Though it's a little more complicated.  OSX 10.4+  
has a true TclTk 8.4 Aqua, but 10.3- only appears to be, but is really  
X11 (and it's the old v8.3).  So we can't make any assumptions about  
the header locations.

To make it simple for the user, tests for /Library/Frameworks/ 
Tcl.framework then /System/Library/Frameworks/Tcl.framework[/Versions/ 
8.4] would be needed to get the appropriate -I flags.  The framework  
flags are simple because no path is needed - the linker looks first  
in /Library/Frameworks, then /System/Library/frameworks, so a user 8.5  
would override the system's.

Disabling/uninstalling /Library/Frameworks is simple, if a user wanted  
to build GRASS for the system framework.
