Components problem on 1.1.6 (Routing Error)

I am running Rails 1.1.6 on a Debian Etch System updated 20060917.
Ruby 1.8.4.

I have created a ruby app and inside it a component, following the
documentation on Peak Obsession

When the component is created, if I go to
http://localhost:3000/my_component, I get a Routing Error:
Recognition failed for “/my_component”

I have tried imitating the rails components video, and the same thing
happens.

Is this a bug in Rails or is it something I have done incorrectly?

Regards,
