Laravel 4 Cannot find Class DB - php

Question

Problem: I'm trying to bootstrap L4 framework for some files (php-resque workers at app/workers) to use, but the workers dont seem to be able to find the class DB on a line that used DB::table('tablename').... composer dumpautoload does not help.
Did the bootstrap I'm using not load the DB classes? It seemed to have loaded the worker classes.
Failed L4 Bootstrapping
<?php
// Bootstrap the laravel environment for our resque workers.
require __DIR__.'/bootstrap/autoload.php';
error
PHP Fatal error: Class 'DB' not found in /var/www/dev/app/libraries/test.php on line 50

You could try to:
1) Load the Composer autoload file, located in vendor/autoload.php (you are actually calling the laravel one)
2) Replicate the calls in the public/index.php file in your test.php file, specifically:
require __DIR__.'/../bootstrap/autoload.php';
$app = require_once __DIR__.'/../bootstrap/start.php';
$app->run();
$app->shutdown();
Edit: after further inspection, you could try to do this with a bare minium:
<?php
require '../vendor/autoload.php';
use Illuminate\Support\Facades\DB as DB;
// Test the DB Instance
$dbInstance = new DB;
var_dump ($dbInstance);
will output
object(Illuminate\Support\Facades\DB)[2]
