  AFFECTS: All GTK+2 and GNOME users
  AUTHOR: gnome@FreeBSD.org

  GNOME has been updated to 2.16. All GTK+2 and GNOME components have
  been moved from X11BASE (/usr/X11R6) to LOCALBASE (/usr/local). To
  upgrade your GNOME desktop or/and other applications you will need
  to use either sysutils/portupgrade or sysutils/portmaster. To use
  portmaster, make sure you have least 1.9 version to have the
  upgrade succeed.

 Portupgrade users:
  pkgdb -Ff
  portupgrade -rf pkg-config\*

 Portmaster users:
  portmaster -r pkg-config\*
