title: How to use composer with phpbrew?
body: <p>I installed phpbrew to use php 5.4 in Ubuntu 14.04. It works fine, except when I try to use composer, which ignores phpbrew and installs dependencies related to php 5.5.</p>
  
  <p>Is there a way to force composer to be compatible with phpbrew config? 
  I trying to add: php: "5.4" in my composer.json, but it says that this requirement is not possible with my php version.</p>
