PHP SDK Facebook on EC2 instal not working

[arbitrageur]

I'm on EC2, and for some reason my require to the Facebook PHP SDK is failing.

require __DIR__ . '/autoload.php';

use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;

use Facebook\HttpClients\FacebookCurl;
use Facebook\HttpClients\FacebookCurlHttpClient;

My guess is somehow it's misconfiguration, with autoload having a fatal error and silently failing. It's working on localhost, however. Any ideas, and where can I view my EC2 PHP error logs?

Thanks
