Should I force the upgrade?

Latest port is 5.0.1 and why this happen?

<piggy@freebsd8>/usr/ports/archivers/xz # sudo portmaster xz
Password:

===>>> Currently installed version: xz-5.0.0
===>>> Port directory: /usr/ports/archivers/xz

	===>>> This port is marked IGNORE
	===>>> is already in the base system

	===>>> If you are sure you can build it, remove the
	       IGNORE line in the Makefile and try again.

Xz compression was recently added to the base so there's no need to install the port.

In other words: simply pkg_delete(1) it and move on.
