That gives me a list of 24 packages.  Am I meant to actually run
python-updater without the -p, here?

I do emerge --depclean -v -p.  It says I should run emerge -uDN @world
first.  I'm a bit apprehensive about this, since the world update says it
would reemerge 138 packages (I'm not sure whether this is top-level
(whatever that means) packages or the real total).  In that list are 3
blockages I don't know wha do do with.  My experience suggests this will
not work smoothly, and I'll likely be left with a non-working (or even a
non-bootable) system.

How come?  Well, I started my installation in February 2010, and with one
thing and another, didn't get it finished, so it went into cold storage
until a month ago.  I've had so much trouble trying to get updated, that
it might be better to start again from scratch with a new stage3 (or even
a new installation CD).  This would surely leave my home directory and
suchlike untouched.  What do you think?
