[R-SIG-Mac] Tcl/Tk

[Dan Putler]

Hi Denis,

Was X11 running before you launched R? The error message suggests to  
me it wasn't running.

It is extremely unlikely you will need to re-install OS X. Although,  
I can imagine you needing to build GRASS from source on your machine  
with appropriate configure options to get it to use X11 Tcl/Tk  
instead of using Apple's version.
