Replace that with just
setpgrp;
This does the same thing and will work on all systems.
I think there's a bug here. Perl is expecting a pgrp arg of 0 to mean
$$, but it doesn't allow an explicit $$. Even this seems a little odd,
as on neither system I've got available at the moment is it mentioned
that a 0 pgrp means getpid() (they both mention that a 0 pid means
getpid(), though).
