 Minix has it's own X11 package ( minix/x11 ) which installs to
 /usr/X11R6. We're currently using x11-6.8.2. Below is a link to that
 package in our source repository...

 From the author of that code, Gautam B.T.:
 
 PKG_DESTDIR is set by pkg_add and pkg_delete when called with the -P
 option. Without these changes packages installed using the -P option
 would have a +DIRS script that manipulates the wrong set of
 directories.
 
 To explain a little on what's going on: Packages have install and
 desintall scripts that are run by pkg_install tools before and after
 installation and deletion. Because of this the +DIRS script which is
 generated from the mk/pkginstall/dirs file gets executed. Now pkg_add
 can be called with -P option to ask it to install stuff in a different
 root directory. When this is done pkg_add sets the PKG_DESTDIR
 variable. Earlier, the scripts just ignored this variable and these
 changes make them honor it.
