Puppet users - Nov 2008 - introduction with david's munin module question

Hi all,
I am new to puppet and also newcomer in this group.
I heart good things about puppet and I decided to give it a try 2 weeks now.
After reading various documentation, I began using the complete
configuration collection of puppet modules (thanks to David).
But I have a problem with the munin module. It works fine, except that it
seems to not export virtual ressources. Let me give more detail about my
configuration:
I use puppet version 0.24 on debian etch.
here is my puppet.conf file content
[main]
logdir=/var/log/puppet
vardir=/var/lib/puppet
ssldir=/var/lib/puppet/ssl
rundir=/var/run/puppet
factpath=$vardir/lib/facter
pluginsync=true

[puppetmasterd]
templatedir=/var/lib/puppet/templates

runinterval = 60
storeconfigs=true
dbuser=puppet
dbpassword=puppetpwd
dbadapter=mysql
dbserver=localhost

my fileserver.conf file
[files]
  path /etc/puppet/files
  allow 192.168.127.0/24
  allow 127.0.0.1/8

[modules]
  allow 192.168.127.0/24
  allow 127.0.0.1/8

[plugins]
  allow 192.168.127.0/24
  allow 127.0.0.1/8

where 192.168.127.0/24 is my network (openvz virtual hosts).
manifests/site.pp file
# site.pp

$munin_allow=''192.168.127.103''
import "modules.pp"

where manifests/modules.pp has
# modules.pp

import "common"
import "munin"

and finally manifests/nodes.pp
# nodes.pp

node puppet {
        include munin::client

}

node backuppc {
        include munin::client
}

node munin {
        include munin::host
        include munin::client
}


I followed all the other instructions given in munin and common modules
READMEs.
But when I run on the master the following command:
puppetd --server puppet.cm.auf --waitforcert 60 --test
all is fine, but I can''t see any exported resource in the database.
But if I add the following line in the nodes.pp file for the node
representing the puppet master
        munin::plugin { df_abs: }
so that it looks like this

node puppet {
        include munin::client
        munin::plugin { df_abs: }
}
and rerun the above command, I have this error message
puppet:/etc/puppet# puppetd --server puppet.cm.auf --waitforcert 60 --test

warning: Not using cache on failed catalog

Can someone help me fixe this?
Thank you in advance.

The only resource exported and collected by the munin module is the 
${NODESDIR}/${name}_${munin_port_real} File in munin::register, which is 
created by munin::client and collected by munin::host.

There were some recent changes to export/collect (which is still 
experimental) and I''m not 100% sure whether or not this would be
affected.

The df_abs plugin is in the set of automatically defined plugins and 
puppet rightly complains that it doesn''t want to manage the plugin
twice.
