    Not done.  When I do this with -p, I get wierdnesses.  emerge wants
    to install cifs-utils and samba (why, I can't fathom) and says they
    have mutual dependencies.  It also wants to update
    gnome-control-center to gnome-3.

    Then it complains about (mainly) gnome stuff, alleging it should be
    updated to gnome-3.8 versions.  Hmm.

    Not done in a million years.  I do this with -p, then I see 289
    packages need removing.  How important is this?  (or is my last post
    the answer to this question?)

    I tried this, and it reported "everything up to date".
