All of my Travis builds failed because my `composer` dependencies are not installed (the `before_script` step seems skipped).

Here is my `.travis.yml`:

```
language: php
sudo: required
php:
    - 5.4

before_script:
    - composer install --dev

script:
    - phpunit -c app

```

I'm sure this is something I missed but I'm not sure what. [This](https://api.travis-ci.org/jobs/99753313/log.txt?deansi=true) is my last build log.
