Copied Laureon's mod and the following error occurs

Warning: main(./auth.php): failed to open stream: No such file or directory in /home/xxxx/public_html/xxxxx/customer/myaccount.php on line 2

here is the php file

<?
require "./auth.php";
require $xcart_dir."/include/categories.php";
$smarty->assign("main", "myaccount");
$smarty->assign("location",$location);
$smarty->display("customer/home.tpl");
?>

Anyone know how to fix the error
