This sounds like problems with source inconsistency. If you csup
something that has files that were loaded from some other source, csup
won't delete files that are no longer in CVS. csup will only delete
files it created.

I suggest that you delete the entire source tree the first time you
update after a new install so that this does not happen. This applies to
both src and ports.

FWIW, my T43 has the same problem. I'd love to see a solution to this
one!

Scott has just committed several fixes that should take care of this.

Same csup issues as with src, but, because of the way patches are
heavily used in ports, far more likely to bite. I no longer install
ports from the distro at all. I just csup them after I install. This
used to be a pain when cvsup had to be installed, but csup is in the
base system, so it's easy now. (Probably portsnap would work even better,
but I still have not gotten around to trying it.)
