I don't know where you come up with that idea.

The buildlink.mk files include lines of the form:

EVAL_PREFIX+=           BUILDLINK_PREFIX.gtk=gtk
BUILDLINK_PREFIX.gtk_DEFAULT=   ${X11PREFIX}

(that was taken from x11/gtk's buildlink.mk file).

The EVAL_PREFIX section is defined in bsd.pkg.mk, and uses pkg_info
to get the installed prefix of the gtk package. I personally went
to a lot of trouble to implement the EVAL_PREFIX functionality in
the first place.

To quote from pkgsrc/Packages.txt

* If xpkgwedge is installed, it is possible to have some packages installed in
   X11BASE and some in LOCALBASE. To determine the prefix of an installed
   package, the EVAL_PREFIX definition can be used. It takes pairs in the
   format DIRNAME=<package>, and the make(1) variable DIRNAME will be set
   to the prefix of the installed package <package>, or ${X11PREFIX} if the
   package is not installed.

   This is best illustrated by example.

   The following lines are taken from pkgsrc/wm/scwm/Makefile:

        EVAL_PREFIX+=   GTKDIR=gtk+
        CONFIGURE_ARGS+=        --with-guile-prefix=${LOCALBASE}        \
                                --with-gtk-prefix="${GTKDIR}"           \
                                --enable-multibyte
   
   Specific defaults can be defined for the packages evaluated using
   EVAL_PREFIX, by using a definition of the form:

        GTKDIR_DEFAULT= ${LOCALBASE}
   
   where "GTKDIR" corresponds to the first definition in the EVAL_PREFIX pair.

Please check your facts before you start asking questions like this.
