I set PREFER.ncurses=pkgsrc but mk/buildlink3/bsd.builtin.mk has:

.for _pkg_ in ${BUILDLINK_PACKAGES}
PREFER.${_pkg_}?=       pkgsrc
.  if !empty(PREFER_NATIVE:M[yY][eE][sS])
PREFER.${_pkg_}=        native
.  endif

So it is immediately reset to native.

Should all of the following:
.for _pkg_ in ${BUILDLINK_PACKAGES}
PREFER.${_pkg_}?=       pkgsrc
.  if !empty(PREFER_NATIVE:M[yY][eE][sS])
PREFER.${_pkg_}=        native
.  endif
.  if !empty(PREFER_PKGSRC:M[yY][eE][sS])
PREFER.${_pkg_}=        pkgsrc
.  endif
.  if !empty(PREFER_NATIVE:M${_pkg_})
PREFER.${_pkg_}=        native
.  endif
.  if !empty(PREFER_PKGSRC:M${_pkg_})
PREFER.${_pkg_}=        pkgsrc
.  endif
.endfor

use ?= instead?

I think they should because PREFER.${_pkg_} would only be defined if
someone really wanted it.

I will test this for awhile ...
