The main focus of this is the bundling step in the OSX app makefile.   
To make sure that the configured tcltk is available to nviz, and to  
avoid confusion with the system tcltk at runtime (which is where  
Michael was having problems), I bundle tcltk into the app package.  I  
thus need to know the version for copying tclsh, wish, the library and  
tcl library folder, all of which have the version in the name, and by  
default tcltk doesn't install unversioned symlinks.

I currently have 8.4 hardcoded in the makefile, with an external shell  
variable to change it to 8.5 if desired.


Hmmm, I see one possibility - check the configured tclConfig.sh,  
though strangely that doesn't install with execute perms... says  
something about being "included" by extension configure scripts... I  
can grep it I suppose... I'll try that.
