Ports with a broken PKGORIGIN: textproc/libxml2-reference

[erwin at FreeBSD.org]

** The following ports have an incorrect PKGORIGIN **

 PKGORIGIN connects packaged or installed ports to the directory they
 originated from. This is essential for tools like pkg_version or
 portupgrade to work correctly. Wrong PKGORIGINs are often caused by a
 wrong order of CATEGORIES after a repocopy.

 Please fix any errors as soon as possible.
