Thanks.  When I removed the full pathname definition of GRASS_WISH, the
-tcltk option worked.  

It seems that GRASS_WISH is an over specification ... given the grass5
man page suggests using the PATH environment variable to define the path
to wish and suggests using a symbolic link to handle variants of the
wish filename.

Thanks again,
