Following up on an Old message, while trying to get BIND 9.21.14
to build & work on my system:
> Add

That's actually wrong. The latter -D will override the former,
and the rpath adjustment is therefore ignored. By the looks of
it they need to be specified with one -D, like so:
-Dc_link_args='-Wl,-rpath=$ORIGIN/../lib -Wl,-z,noseparate-code'
So the recipe for building and installing using "build-dir" as
the build dir on NetBSD with sufficiently new ld.elf_so:
meson setup build-dir \
-Dtracing=disabled \
-Dc_link_args='-Wl,-rpath=$ORIGIN/../lib -Wl,-z,noseparate-code'
meson compile -C build-dir
meson install -C build-dir
(The turning off tracing is for dtrace support which if left
enabled ends up with lots of undefined symbols. I think I asked
where those were supposed to come from, but got no response to
that question.)

I get so negative vibes from your comments. Why? I'm just
trying to solve problems here, and they're not all of my own
making.
As for not including /usr/local/lib in the RPATH by default
actually stems from security concerns. Someone might have more
relaxed permissions for that lib directory than for "system
directories", and being able to trick programs into loading a
rogue .so would be bad.
Also, pkgsrc frowns on (and removes!) the use of $ORIGIN, for
somewhat of the same reasons: a binary may be moved, and the
neighboring ../lib directory might be abused. RPATH must
therefore be explicitly specified, could be done via $PREFIX
which is expanded at build time.
