zend framework components DB can't find class Zend_Paginator_Adapter_DbTableSelect

I'm using some Zend libraries outside of the Zend Framework in a small project. I'm using Zend_Db and Zend_Paginator but when I'm trying to set up the pagination using Zend_Paginator_Adapter_DbTableSelect I get an error that it can't find the class.

Fatal error: Class 'Zend_Paginator_Adapter_DbTableSelect' not found in C:\xampp\htdocs\php_testing\zend\zend_db\index1.php on line 65 Here is my code:

<?
require_once 'Zend/Db.php';
$config=array(
    'adapter' => 'PDO_MYSQL',
    'hostname' => 'localhost',
    'dbname' => 'dm_xxxx',
    'username' => 'un',
    'password' => 'pw'

);
$db=Zend_Db::factory($config['adapter'], $config);
$select=$db->select()
        ->from('photocontest__photos', array('*'))
        ->order('created')
        ;    
require_once 'Zend/Paginator.php';
$currentPageNumber = ($_GET['page'] > 0)?$_GET['page']:'1';
$totalNumberOfItems = 11;
$itemsPerPage = 5;
$pageRange = 10;

$adapter = new Zend_Paginator_Adapter_DbTableSelect($select);
$paginator = new Zend_Paginator($adapter);
$paginator->setCurrentPageNumber($currentPageNumber);
$paginator->setItemCountPerPage($itemsPerPage);
$scrollType = 'Sliding';
$paginator = get_object_vars($paginator->getPages($scrollType));

foreach($paginator AS $item){
    echo $item->title.'<br>';
}
?>

thanks
