ComponentLookupError

[David Ray]

Working with the following versions:

plone 4.0
collective.amberjack.core 1.1a-Unreleased (trunk)
collective.amberjack.portlet 1.1a-Unreleased (trunk)
collective.amberjack.plonetours 1.0

Post installation, the portlet fails to render, due to a ComponentLookupError:
