Travis CI runs their VMs on Ubuntu 14.04 images, which is an issue for us because it does not contain GDL on its repository, forcing us to download and install all dependencies one by one.

One solution would be running an updated version of Ubuntu inside a Docker container, as it is suggested in travis-ci/travis-ci#5821
