pkgconf-0.8.9 conflicts...

[Modulok]

List,

I've been seeing a lot of this recently when I try to install new ports. The
following is on a fresh install of FreeBSD 9.0 Release, when I tried to install
linux-f10-flashplugin11 from ports. (It happens with several other packages
too)::

    Stop in /usr/ports/www/linux-f10-flashplugin11.

        pkgconf-0.8.9 conflicts with installed package(s):
        pkg-config-0.25_1

So, I try this::

    pkg_delete pkg-config-0.25_1

But of course I can't deinstall it because several hundred already installed
require it.

Suggestions?
