No encuentro $cfg['PmaAbsoluteUri']

Estoy tratando de configurar phpmyadmin por primera vez; ya he logrado instalar php, mysql y apache.. Y funciona ok.
He descargado y descomprimido el archivo "phpMyAdmin-3.1.5-all-languages.zip" en el root de mi sitio, y al tratar de configurar el archivo "config.inc.php" (renombrado de config. Sample. Inc.php), y siguiendo las instrucciones de muchos sitios, debo modificar "$cfgPmaAbsoluteUri", pero simplemente NO LO ENCUENTRO.
El codigo que viene en config. Sample.inc.php es:
<?php
/* vim: set expandtab sw=4 ts=4 sts=4: */
/**
* phpMyAdmin sample configuration, you can use it as base for
* manual configuration. For easier setup you can use setup/
 *
* All directives are explained in Documentation.html and on phpMyAdmin
* wiki <http://wiki.phpmyadmin.net>.
