Problems with PHP YAML in Travis CI

Question

Edit: I believe the problem is that YAML does not work with 5.4 / 5.5.

I have a library that is configured in Travis CI and uses the PHP YAML PECL extension. However, I can't get the YAML extension to work in Travis and PHP 5.4, and I'm curious if anyone else has it? No Googling scope solved my problem.

Here is the conclusion of Travis:
