You probably going to shoot me for this but all of the above is now
taken care of automatically by the 'ant setup' target. Niclas updated
this yesterday and it seems to be reasonably solid.

It works because it has not repository related artifact dependencies.

Sure - and apologies up-front, this is all sort of coming together as we
speak. The problem your seeing is that the application repository cache
used by merlin is not the same as the cache used by magic. To get
things sorted you need to synchronize these two. The following
instructions should achieve that. I imaging the next release will have
a bundled and totally synchronized Merlin + Magic.
Steps:
1. Define AVALON_HOME to refer to MAGIC_HOME
2. Rename ${magic.home}/main to ${magic.home}/repository
3. Add the following line in a file name ${magic.home}/user.properties
magic.cache = ${magic.home}/repository
<snip>
After doing the above make sure that the following statement when using
-info shows that the merlin.rpository is referencing the magic
repository.
> ${merlin.repository} == /home/mark/.avalon/repository
Cheers, Steve.
