[GRASSLIST:5498] libtk8.4.dylib

[Michael Mio]

Hi again. It seems like every time I fix one thing, something else 
happens. I was trying to use the nviz tool, and I got this following 
error:

dyld: /usr/local/grass5/etc/nviz2.2/NVWISH2.2 can't open library: 
/usr/local/lib/libtk8.4.dylib  (No such file or directory, errno = 2)

     (file "/usr/local/grass5/bin/nviz" line 16)


It seems like I am missing the libtk8.4.dylib file? Is there somewhere 
I need to go to download it? Thanks again for the help.

Cheers,

Mike
