@loicfrering @michaelklishin could you please review this ? Actually, I would propose to refactor even more and directly bundle `bison` and `libreadline` tricks into `php` cookbook... what do you think?

@joshk while being bitten by this problem, I noticed following [travis-images bootstrap step](https://github.com/travis-ci/travis-images/blob/master/lib/travis/cloud_images/vm_provisioner.rb#L25). Shouldn't we shift the installation of these apt packages to travis-cookbooks ?
