0.8RC1 fails to build site-author with errors such as the following in broken-links.xml:

<link message="Could not find component for role: [org.apache.cocoon.components.modules.input.InputModule/defaults] (Key='org.apache.cocoon.components.modules.input.InputModule/defaults')" uri="procedures/release/How_to_release.html">
    <referrer uri="linkmap.html"/>
</link>

a seed-sample works just fine.

Going to bed - will pick up tomorrow.
