__DIR__ undefined on php < 5.3

[Fournier Erwan]

Chive doesn't work anymore on php version < 5.3

Notice: Use of undefined constant __DIR__ - assumed '__DIR__' in /xxx/chive/index.php on line 33

Warning: CApplication::require(__DIR__/protected/config/main.php) [capplication.require]: failed to open stream: No such file or directory in /xxx/chive/yii/base/CApplication.php on line 100

Fatal error: CApplication::require() [function.require]: Failed opening required '__DIR__/protected/config/main.php' (include_path='.:/usr/share/php:/usr/share/pear') in /xxx/chive/yii/base/CApplication.php on line 100

Something like this does the job :

if (!defined('__DIR__'))
 define('__DIR__', dirname(__FILE__));

Same problem here. PHP 5.2.17
