Upgrade to 2.6….where’s wp-load.php?

I’m using the Automatic Upgrade plugin to upgrade a client’s WP installation to the latest and it gives me errors on the wp-admin/admin.php file looking for a file called wp-load.php. Sure enough, I download admin.php and find this right near the top:

if ( defined(‘ABSPATH’) )
require_once(ABSPATH . ‘wp-load.php’);
else
require_once(‘../wp-load.php’);

if ( get_option(‘db_version’) != $wp_db_version ) {
wp_redirect(admin_url(‘upgrade.php?_wp_http_referer=’ . urlencode(stripslashes($_SERVER[‘REQUEST_URI’]))));
exit;
}

But there’s no such file there called wp-load.php. Where is it?
