You must set up the project dependencies, run the following commands:
curl -s http://getcomposer.org/installer | php
php composer.phar install
walterheck@casa:~/git/infra$ php composer.phar install
Could not open input file: composer.phar
instead, this works:
walterheck@casa:~/git/infra$ composer install
