invalid component definition, can't find coldbox.system.Coldbox

This is a new Coldbox installation on Railo 3.3 running on Ubuntu. I
have not been able to access the samples just to verify that it is
functional. I abandoned this attempt for the moment to use the built
in application installer then move the Coldbox 3.5 version over it and
to a reinit.

I simply would like to know what I did wrong. I had the coldbox
directory under /var/www/Railo/, which was mapped and tested against a
boring index.cfm page.

Here is the full error.
Railo 3.3.1.000 Error (expression)

Are you using inherited or non inherited Application.cfc, if you are using inherited you need to define the mapping for coldbox in railo.
