I see no problem with adding "use lib '.';" provided you:

• preceed it by BEGIN { chdir("/abs/path") or die "Can't chdir to /abs/path: $!\n" }
• be very careful to prevent "others" from getting "write" access to /abs/path

This last item could even involve checking the permissions on the directory from within the script.
