comparison to stable/grizzly is not numeric

the current d-g code uses -ne which is an explicitly numeric
opperator. Make this != to do the right thing with strings. Use variable
that is local to setup_localrc().
Without this there we get:

[[: stable/grizzly: division by 0 (error token is "grizzly")
