Remove dependency on xz - How?

[Lars Eighner]

archivers/xz is mark IGNORE because xz is now in the base system (8.2)

Numerous other ports won't build because they believe they depend on xz (or
on a port that depends on xz)

I'd like to remove the dependencies on xz from the pkgs database.

pkgdb -s /xz-5.0.0// won't work as the slash notation might suggest it would
because -s does not accept a  'empty argument'

I am afraid to remove the xz package because it seems to me it would delete
the base system xz -- and I don't want to make world if I can avoid it.

Is there some sensible way to do this?
