 * An update to portage is available. It is _highly_ recommended
 * that you update portage now, before any other packages are updated.
 * Please run 'emerge portage' and then update ALL of your
 * configuration files.
 * To update portage, run 'emerge portage'.

root ~ # emerge portage
!!! ARCH is not set... Are you missing the '/etc/make.profile' symlink?
!!! Is the symlink correct? Is your portage tree complete?

So it seems that emerge portage fails.
Also I do'nt understand this:

.. then update ALL of your
 * configuration files.
