Laravel 5 Install encounters RuntimeException with Symfony's HttpFoundation

I am using php 5.4 and installing laravel 5.0.*.

When running the composer install, it fails at the end with this error message.

[RuntimeException]

  Could not scan for classes inside "C:\portal\vendor/symfony/http-foundation/Symfony/Component/HttpFoundation/Symfony/Component/HttpFoundation/
  Resources/stubs" which does not appear to be a file nor a folder

It seems to have a problem with the classmap loading in the symfony/http-foundation composer.json which looks like this:

 "autoload": {
        "psr-0": { "Symfony\\Component\\HttpFoundation\\": "" },
        "classmap": [ "Symfony/Component/HttpFoundation/Resources/stubs" ]
    },

It looks like it having a conflict with the psr0 and classmap loading leading to the class map looking in:

C:/portal/vendor/symfony/http-foundation/Symfony/Component/HttpFoundation/Symfony/Component/HttpFoundation/Resources/stubs

instead of

C:/portal/vendor/symfony/http-foundation/Symfony/Component/HttpFoundation/Resources/stubs

The main projects composer.json looks like this:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "laravel/framework": "5.0.*",
        "guzzlehttp/guzzle": "5.3.*"
    },
    "require-dev": {
        "phpunit/phpunit": "~4.0",
        "phpspec/phpspec": "~2.1"
    },
    "autoload": {
        "psr-4": {
            "App\\": "app/"
        }
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php -r \"copy('.env.example', '.env');\"",
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist",
        "platform": {
            "php": "5.4.44"
        }
    }
}

Any ideas on how to get past this issue?

Other things I have already looked at:

• http://ift.tt/2dmRnQh
• Symfony 2 -> Composer and CloudControl

I have already tried clear vendor/cache and re running install.
