Ideally, I think GRASS needs to detect a framework TclTk Aqua

Presumably this would be handled similarly to OpenGL, which already
has suitable configure checks.
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.
Something else to keep in mind. The header I posted is needed by Togl
I think. But I also think that it is 8.5 only.
