Hello, I appreciate this may be a problem with Doctrine instead of Swagger but whenever I try to run Swagger from the CLI I get the following error: ``` bash ~/Github/swagger-example » php docs.php alexbilbie@macbook-pro == extension: xcache == => not installed, requires a PHP version < 5 (5.4.9 installed) == extension: memcache == => Command 'wget http://pecl.php.net/get/memcache-2.2.6.tgz > /dev/null 2>&1' failed !% ``` All docs.php contains at the moment is the following: ``` php <?php include 'vendor/autoload.php'; use \Doctrine\Common\Cache\PhpFileCache; $path = '/Users/alexbilbie/Github/swagger-example'; $cacheDir = 'cache'; $swagger = new Swagger\Swagger($path, null, new PhpFileCache($cacheDir, '.cache')); ``` Do you have any ideas? Thanks
