Remove /usr/local? I must have missed this in the documentation,
can you point me please?

I thought the whole reason for living under /opt/local was *not* to
interfere with /usr/local. How exactly does having /usr/local interfere?
Things from macports silently picking up things from /usr/local?
Is that the problem?

Yes, I have things in /usr/local too - stuff that is _not_
in macports (otherwise I would just install it from macports - and
have it installed under /opt/local), and local admin tools.
It would be a PITA to make that disappear during every
macports action (not that it's very often) ...
