Your code is perfectly valid. The error sounds like you are not running it using PHP5.3 which is required when using closures.

The pre-5.3 way would be:

private function emailRule($email)
{
    return ( filter_var($email, FILTER_VALIDATE_EMAIL) === FALSE ) ? FALSE : TRUE;
}

public function email($message='')
{
    $message = ( empty ($message) ) ? '%s is an invalid email address.' : $message;
    $this->set_rule(__FUNCTION__, array($this, 'emailRule'), $message);
    return $this;
}
