When trying to run the tests on Travis, I get the error above? See also: https://travis-ci.org/lsolesen/classic/builds/14445587

In this line https://travis-ci.org/lsolesen/classic/builds/14445587#L226

$ sudo drush --root=$PWD/drupal runserver --server=builtin 80 &
$ sleep 3
sudo: drush: command not found

It seems that the runserver command for drush is not found?
