Why does puppet magically install apache2 for me?

I'm new to puppet and thought to try something out. This simple tryout manifest should install PHP and then NGINX with no modification to any config files.

But every time I try it out I get unwanted apache2 installed. I'm on Ubuntu Server 12.04, using "http://apt.puppetlabs.com precise main". If anyone can spot the culprit I would apprechiate it. How to debug this kind of issue with puppet ?

Things I tried.. after apt-get purge apache* php* nginx*

  1. Install same packages via apt-get. WORKS properly.
  2. Apply manifest in steps with multile commenting of below sections /* */. This also worked, apache2 did not get installed.
  3. Search for "apache" string from from puppet "--debug" output. With using full manifest. String not found, but apache2 got installed anyway.
  4. Removed #hiera_include('classes') from sites.pp and put this manifest directly to sites.pp. Same results, apache2 got installed.

Manifest:

###### APT
include "apt"

apt::ppa { 'ppa:ondrej/php5': }
apt::key { "ondrej": key => "E5267A6C" }

apt::ppa { 'ppa:nginx/stable': }
apt::key { "nginx": key => "C300EE8C" }

###### PHP

$php_packages = [
"php5", 
"php5-fpm",
"php5-common", 
"php5-cli", 
"php5-curl",
"php5-ldap",
"php5-mysql",
"php5-pgsql", 
"php5-gd",
]

package { $php_packages:
    ensure  =>  'installed',
    require => Apt::Ppa['ppa:ondrej/php5' ],
    install_options => ['--no-install-recommends'],
}

service { 'php5-fpm':
    ensure => running,
    require => Package['php5-fpm'],
}

###### NGINX

package { 'nginx':
    ensure  =>  'installed',
    require => [
        Package['php5-fpm'],
        Apt::Ppa['ppa:nginx/stable' ],
        ],
    notify => Service['php5-fpm'],
    install_options => ['--no-install-recommends'],
}
package { 'apache2':
    ensure => "purged",
}

service { 'nginx':
    ensure => running,
    require => Package['nginx'],
}

2) Check apache folder... Why is apache2 installed at all ???

4) Check apache folder... Ok this I understand, the ensure => "purged" takes affect.

?#> la /etc/apa*

    Your manifest is installing php5, and that depends on apache. I got these versions/dependencies from Debian 6.0 but 12.04LTS will be similar
