I wan't to use a specific repo but when I run 'puppet agent' use Epel repo

[Luis León]

For example with this code

yumrepo { 'erlang':
    baseurl     => '[url_repo]',
    enabled    => 1,
    gpgcheck => 0,
  }

  package {'erlang':
    ensure  => installed,
    require  => Yumrepo['erlang']
  }

I look for solutions that disable epel (and that's what I used) but is there any solution to use a specific repo?

Thanks!!
Luis
