You can try this patch.  It puts the cart before the horse
though, so signals could get delivered in a different
order.

Martin, is there some magic to building open-office.  My
ports tree is pristine and I recently rebuilt X, KDE,
and mozilla using portupgrade.  This was without any
previous /usr/local or /usr/X11R6 (I mean clean!).
portinstall just returns and does nothing:

  $ sudo portinstall -NR editors/openoffice
    <silently thinks for a couple of minutes>
  $
