How to install system package and gem with the same name? [closed]

edit

I would like to install redis debian package and ruby wrapper for redis, unfortunately both have same name.

Basically the code looks like this:

  package { 'redis':
    ensure   => 'installed',
    name     => 'redis',
  }

  package { 'redis-gem':
    ensure   => 'installed',
    name     => 'redis',
    provider => 'gem',
  }

I wasn't able to convince puppet, that those are different resources:

Puppet::Parser::AST::Resource failed with error ArgumentError: Cannot alias Package[redis-gem] to ["redis"]; resource ["Package", "redis"] already declared

Is there a way how to bypass this?
