Help with Swazoo 1.0

I'm trying to get Swazoo 1.0 running on a fresh image of D6 Pro but
can't get it started. The test is as follows:

   site := Site new name: 'test'.
   site host: 'localhost' ip: '127.0.0.1' port: 8888.
   SwazooServer singleton addSite: site.
   site start.
   resource := HelloWorldResource new uriPattern: 'helloworld.html'.
   composite := CompositeResource new uriPattern: '/'.
   composite addResource: resource.
   (SwazooServer singleton siteNamed: 'test') addResource: composite.

Can anyone point out what else is needed to get it running?

Regards,
Glenn
