[GRASS-dev] Re: GUI support for TclTk 8.5

[William Kyngesburye]

Ah, it looks like --enable-xft is a new option in Tk 8.5, and is  
enabled by default.  In the working Tiger TclTk 8.5 GUI, the menu  
fonts look nice, compared to the 8.4 GUI.

So, disabled xft and now TclTk 8.5 GUI works on Leopard.  NVIZ also  
works.  NVIZ still won't run on Tiger though.
