Trouble upgrading to Laravel 4.1 - laravel-4

Question

I'm having trouble upgrading to 4.1.
I've followed the upgrade guide in the docs but when I run composer update, I get the following error:
Script php artisan clear-compiled handling the post-update-cmd event returned with an error
PHP Fatal error: Call to undefined method
Illuminate\Foundation\Application::bindShared() in
/site/vendor/laravel/framework/src/Illuminate/Queue/FailConsoleServiceProvider.php
on line 26
{"error":{"type":"Symfony\Component\Debug\Exception\FatalErrorException","message":"Call
to undefined method
Illuminate\Foundation\Application::bindShared()","file":"/site/vendor/laravel/framework/src/Illuminate/Queue/FailConsoleServiceProvider.php","line":26}}Script
php artisan clear-compiled handling the post-update-cmd event returned
with an error
[RuntimeException]
Error Output: PHP Fatal error: Call to undefined method
Illuminate\Foundat ion\Application::bindShared() in /site/vendor
/laravel/framework/src/Illuminate/Queue/FailConsoleServiceProvider.php
on l ine 26
However, if I create a new project and use the same composer.json file, it runs successfully.
Can anyone point me in the right direction?
Here is the contents of my composer.json file:

Quick update. I've got it to work now. I had a few packages in my workbench directory which each had their own composer.json file. I had to update the require section to read:
"require": {
"php": ">=5.3.0",
"illuminate/support": "4.*"
},
