This will certainly cause duplicate definition problems down the road when dealing with another module that needs php. The thing to do here would be for the observium package to manage its dependencies, then `$default_packages = 'observium'`.

When building the RPM with FPM you can specify -d multiple times, such as `-d php5-cli -d php5-mysql`, etc.

Recommend putting the FPM script on github, too, so nobody forgets how to build between releases.
