Boa Tarde Galera,

estou tentando criar uma estrutura modular baseada nessa aqui http://framework.zen...er.modular.html, tentei utilizar o zend tool mas sem sucesso, ai tentando alterar está apresentando esse erro aqui:

Fatal error: Call to a member function getDefaultModule() on a non-object in /usr/share/php/libzend-framework-php/Zend/Application/Bootstrap/Bootstrap.php on line 89

Bootstrap.php

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{

protected $_frontController = null;

protected function _initFrontController()

{

	// Recebo uma instância do Zend_Controller_Front::getInstance();
	$this->_frontController = Zend_Controller_Front::getInstance();
	// Adicionando o diretorio dos modulos
	$this->_frontController->addModuleDirectory(APPLICATION_PATH . '/modules');
	// Definindo onde estão os controllers
	$this->_frontController->setControllerDirectory(array(
 'default' => APPLICATION_PATH . '/default/controllers',
 'admin' => APPLICATION_PATH . '/admin/controllers'
	));
 }

protected function _initAutoLoad()

{

	$moduleLoader = new Zend_Application_Module_Autoloader(array(
 'namespace' => '',
 'basePath'	=> APPLICATION_PATH
	));

	return $moduleLoader;
}

}

alguém saberia me dizer se está faltando alguma coisa...
