I just upgraded php to PHP 5.3.8 and all concrete5 sites broke :(

There are errors with the zend folder files with includes.

eg. Cache.php
require_once str_replace('_', DIRECTORY_SEPARATOR, $frontendClass) . '.php';
Changed to
require_once "/home/lisa/public_html/concrete/libraries/3rdparty/Zend/Cache/$frontend.php";

eg. File.php line26
require_once 'Zend/Cache/Backend/ExtendedInterface.php';
changed to
require_once '/home/lisa/public_html/concrete/libraries/3rdparty/Zend/Cache/Backend/ExtendedInterface.php';


I see other people have had the same problem but no real answer/fix was given.

Error after php upgrade.
