error while running install.sql in community auth

Code:

-- Trigger updates passwd_modified_at field if passwd modified
--

delimiter $$  <<this line
DROP TRIGGER IF EXISTS ca_passwd_trigger ;
$$           <<this line
CREATE TRIGGER ca_passwd_trigger BEFORE UPDATE ON users
FOR EACH ROW
BEGIN
   IF ((NEW.passwd <=> OLD.passwd) = 0) THEN
       SET NEW.passwd_modified_at = NOW();
   END IF;
END;$$   <<this line
delimiter ;

-- --------------------------------------------------------

The $$ is causing an error when I try to run install.sql in phpmyadmin. A table called New is created but it is empty. What am I doing wrong?
