Trying to update graphics/libglut on current as per UPDATING, and nothing 
happens.

   AUTHOR: x11 at FreeBSD.org

   The libglut library is replaced by the freeglut library.
   Due to shlib version bump all glut users should be rebuild.
   Please follow the instructions below to upgrade.
   # env DISABLE_CONFLICTS=1 portupgrade -vfo graphics/freeglut graphics/libglut
   # portupgrade -vfrx freeglut freeglut"
