dragonfly-2010Q3 unbound dns resolver - linking problem

[Paul Onyschuk <blink@xxxxxxxxxxxxxx>]

Unbound (simple DNS resolver) is available in pkgsrc. I installed
it from binary packages on DragonFly BSD i386 2.8.2, but it breaks on
runtime:

/usr/libexec/ld-elf.so.2: /usr/pkg/sbin/unbound: Undefined symbol
"ldns_key_EVP_ladd_gost_id"

ldd shows that unbound is linked with DragonFly BSD ldns library
instead of pkgsrc version (/usr/lib/libldns.so.1 instead
of /usr/pkg/lib/libldns.so.1). Pkgsrc uses version 1.6.6 of ldns and
DragonFly BSD uses v1.6.4.

Problem is bigger, because path to pkgsrc's ldns is specified in
unbound's makefile:

CONFIGURE_ARGS+=	--with-ldns=${BUILDLINK_PREFIX.ldns}

Probably libtool is doing some kind of magic ;) There is simple, but
dirty way to fix that - changing that line in makefile to:

CONFIGURE_ARGS+=	--with-ldns-builtin

This way, unbound will be compiled statically with ldns provided
with unbound source tree and works perfectly.

Anyone has better solution?
