Any additional information you'd like to impart

If i get this correctly, where is zabbix::web class included there will be installed zabbixapi gem, which is needed for managing resources in Puppetdb. This do not work for me for some reason. And when i try install zabbixapi gem with

package { 'zabbixapi':
    ensure   => 'installed',
    provider => 'gem',
  }

i get Duplicate declaration error, because resource Package[zabbixapi] already exists in zabbix::web.
