   Hello,
   I am trying to upgrade Intel drivers on DesktopBSD using the Package
   manage   following message:
   --->  Installing the new version via the port
   ===>  Installing for xf86-video-intel-2.1.0
   ===>  xf86-video-intel-2.1.0 conflicts with installed package   (s):
         xf86-video-i810-1.6.5_2
         They install files into the same place.
         Please remove them first with pkg_delete(1).   *** Error code 1
   Stop in /usr/ports/x11-drivers/xf86-video-intel.

   If I try to remove 1.6.5_2, I see the following:
   sudo pkg_delete xf86-video-i810-1.6.5_2
   pkg_delete: package 'xf86-video-i810-1.6.5_2' is required by these
   other pa   and may not be deinstalled:
   xorg-7.2
   xorg-drivers-7.2
   Help!!
