I'm struggling with the atom_feed method in a RoR 3 project. The method complains about an 

undefined local variable or method `xml'

error so I tried passing the XML builder as an option to the atom_feed (i e atom_feed({:xml => Builder::XmlMarkup.new})) but when doing so I get a NameError: uninitialized constant Builder exception instead.

Does anyone know why I'm getting either the first or the second exception?
