Puppet users - Dec 2012 - YAML as File resource template Error , "can't convert Hash to String"

Using exported resources I''m trying to have a host export a File
resource
generated from a yaml template, to another host.  The host that gets the 
exported resource is throwing errors like this

err: Failed to apply catalog: Parameter content failed: Munging failed for 
value
{"parameters"=>{"macaddress_p2p1"=>"00:15:17:80:5A:3E",
"macaddress_p2p2"=>"00:15:17:80:5A:3F", 
"macaddress_eth0"=>"00:1E:C9:55:12:C7", 
"macaddress_eth1"=>"00:1E:C9:55:12:C9",
"operatingsystem"=>"CentOS",
"serialnumber"=>"",
"interfaces"=>"eth0,eth1,lo,p2p1,p2p2",
"fqdn"=>"<snip>",
"ipaddress_p2p1"=>"",
"ipaddress_p2p2"=>"", "uuid"=>"",
"ipaddress_eth0"=>"",
"ipaddress_eth1"=>"<snip>",
"productname"=>"",
"operatingsystemrelease"=>"6.3"},
"name"=>"<snip>"} in class content: can''t
convert Hash into String

Here is the parts of the module...

class racktables::export (
  $site,
  $yamls_dir  = ''UNSET''
) inherits racktables::params {

  $yamls_dir_REAL = $yamls_dir ? {
    ''UNSET''   => "${conf_dir}/${site}/yamls",
    default   => $yamls_dir,
  }

  @@file { "racktables_host_${::hostname}.yaml":
    content   => template(''racktables/host.yaml.erb''),
    path      => "${yamls_dir_REAL}/${::hostname}.yaml",
    tag       => "host_yaml_for_${site}",
  }

}

define racktables::instance (
...
) {
<snip>

  File <<| tag == "host_yaml_for_${name}" |>> {
    require   => File[$yaml_exports_REAL],
  }

<snip>
}

Template...

# cat templates/host.yaml.erb
--- 
name: "<%= scope.lookupvar(''::hostname'') %>"
parameters: 
  interfaces: "<%= scope.lookupvar(''::interfaces'')
%>"
  fqdn: "<%= scope.lookupvar(''::fqdn'') %>"
  operatingsystemrelease: "<%=
scope.lookupvar(''::operatingsystemrelease'')
%>"
  operatingsystem: "<%=
scope.lookupvar(''::operatingsystem'') %>"
  productname: ""
  uuid: ""
  serialnumber: ""
<%
scope.lookupvar(''::interfaces'').split('','').each
do |interface| -%>
<% unless interface.eql? "lo" -%>
  ipaddress_<%= interface %>: "<%= 
scope.lookupvar("::ipaddress_#{interface}") %>"
  macaddress_<%= interface %>: "<%= 
scope.lookupvar("::macaddress_#{interface}") %>"
<% end -%>
<% end -%>


Is there some catch to using a YAML file for the template content?  Would 
it be better to use Ruby DSL for the racktables::export class and generate 
a hash -> sort -> to_yaml and have that be set as the content?

Thanks
