* 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:
your /usr/portage directory is probably not mounted properly check that again and then check /etc/make.profile points to a valid directory which will be something along the lines of /usr/portage/profiles/default-linux/<arch>/<version>
