By the nature of the Puppet's language, resources must have a unique
title and must have only one definition.

Quoting http://docs.puppetlabs.com/guides/language_guide.html#resources:

"The field before the colon is the resource’s title, which must be
unique and can be used to refer to the resource in other parts of the
Puppet configuration."

The line above is just a shortcut to this something like this:

package {"php5": .... }
package {"php5-cli": .... }
package {"php5-imagick": .... }

So when Puppet compiles all your manifests, there can be only one
php5-imagick, in your case.
