(or 8.5 if they are 8.5)

This will tell you if it's linked to X11.

NO.  That's the system tcltk.

I just started looking at 8.5.  What I found so far for the aqua  
framework build:

- it includes the private headers we need by default, but in a  
separate subfolder:

Tk.framework/PrivateHeaders

- it does NOT install /usr/local/lib symlinks.  So to account for a  
default tcltk aqua, we need to look into the configure idea I had  
earlier.

- while they have 64bits working for an X11 build, they don't have it  
working for an Aqua build, so we won't get a 64bit tcl-based nviz.


For an immediate fix:

Configure with the --with-tcltk-includes as:

  --with-tcltk-includes="/Library/Frameworks/Tcl.framework/Headers / 
Library/Frameworks/Tk.framework/Headers /Library/Frameworks/ 
Tk.framework/PrivateHeaders" --with-opengl=aqua

you can ignore --with-tcltk-libs.  BEFORE make, edit include/make/ 
platform.make and replace the TCLTKLIBS line with:

TCLTKLIBS = -framework Tcl -framework Tk

then make.
