Note: GRASS_WISH is an actual environment variable, not a GRASS
variable (unfortunately, some of the GRASS documentation confuses the
two).

GRASS_WISH is treated as the base name of the wish program (e.g.
"wish" or "wish8.3"); the startup script looks for that file in each
directory in your current path.

Adding /home/gjs/ActiveTcl/bin to PATH and undefining GRASS_WISH (or
setting it to "wish") should work.

It should probably be changed to allow GRASS_WISH to be a full
pathname.
