Starting from Zend V1.6, I had to make the following 
change in Zend_Translate.php:

   public function setAdapter($adapter, $data, $locale = null, array $options = array())
    {
   /*  <<--
      if (Zend_Loader::isReadable('Zend/Translate/Adapter/' . ucfirst($adapter). '.php')) {
            $adapter = 'Zend_Translate_Adapter_' . ucfirst($adapter);
        }
  --> */
  
  Reasons: this triggers an error because the Zmax adapter canot be read. Hope
  this will be fixed by Zend latter.
