This is the KDE "Akonadi Self test report" shown when an error occurs on
startup and which can be explicitly run in KDE's system settings program.

I totally overlooked that when looking at Dale's test output.
How did that end up being configured for sqlite which is known not to work?
Gentoo didn't pull the sources from the experimental sqlite branch, did they?
Dale, your akonadiserverrc (see other reply) also needs this:
Next version will have support for Postgres, though not tested very well.

The requirement is actually a library shared by Akonadi Server and KDE's
Akonadi client library.
This library is usually installed alongside Akonadi Server, which is why you
get this package/ebuild dependency.

Since Dale's session configuration seems to be highly experiemental without
him knowing, I am almost certain this is a result of one of the compatibility
plugins being loaded.
Dale you can check in KDE's system settings -> advanced tab -> KDE resources.
For Contacts or Calendar, things called "Akonadi Compatibility Resource" or
Basically plugins for KDE's current resource system to get data from Akonadi.
Intended in the long run for keeping compatibility with old applications,
currently disabled in all our releases, only enabled for testing in trunk,
betas and RCs.
Dale writes in another reply that he gets it at login, which most likely means
it is the contact resource plugin, either being used by Kopete or something
like the KRunner "Contacts" plugin.
Removing it through system settings should help here.

I am not totally sure (haven't had time to follow development closely enough
recently), but KMail might require Akonadi for address related stuff in 4.4,
just not for its own data.

As far as I understood the situation with Sesame2 is that the main problem is
its own source, because as a good Java citizen it is using Maven as its build
and dependency system which interferes with Linux distributions' dependency

I think it is called Virtuouso, probably slightly different spelling :)
