An IMHO better solution would be to move sgtool (the Tcl/TK frontend to
sgrep) out of the PATH (say in /usr/lib/sgrep) and install a small wrapper
shell script /usr/bin/sgtool which checks for "wish", calls the
original sgtool or fails with an informative error message.

That's how it is done for xblast, for example.
