Re: Development version of BIND 9 - 9.21.10 with meson build system

Add
-Dc_link_args=-Wl,-rpath='$ORIGIN/..lib' -Dc_link_args=-Wl,-z,noseparate-code

to meson invocation. This might get you going.

So, far, I am not seeing “NetBSD quirks”, but broken base system with linker (ld) allowing options that are broken and a broken dynamic linker. This has nothing to do with BIND 9 and needs to be fixed in NetBSD directly. Also if the base system doesn’t include /usr/local/lib, it probably should add $ORIGIN/../lib to rpath by default and not rely on applications to do that because … reasons.
