Most of the distributions handle the erlang installation automatically.
The garethr/erlang dependency is not needed there and can be added

+### RedHat module dependencies
+To have a suitable erlang version installed on RedHat systems,
+you have to install another puppet module from http://forge.puppetlabs.com/garethr/erlang with:
+
+	puppet module install garethr-erlang
+
+This module handles the packages for erlang.
+To use the module, add the following snippet to your site.pp or an appropriate profile class:

+	class { 'erlang': epel_enable => true}
+	Class['erlang'] -> Class['rabbitmq']
