Hi @Tamerz, thanks for the PR. Can you please rebase after #464 got merged? That should fix the travis errors.

I thought I did this right, but it is still failing. I am not sure why.

Hi @Tamerz, I rebased the branch for you:
The basic steps were:

git clone [email protected]:voxpupuli/puppet-php.git
cd puppet-php
git remote add pr1 [email protected]:Tamerz/puppet-php.git
git fetch pr1
git checkout rhcsldocs
git rebase origin/master

this clones the repo, attaches your fork as another remote, checksout your feature branch and rebases it against our latest master.
