IMHO, someone who knows how to manually hack .a files is in a much better
position to do custom downloading/compiling then those who can barely run
"./configure" and unknowingly end up with an older (possible insecure copy)
of ldns.

Also, if speed is that much of an issue, I recommend upgrading that 32bit
arch to some hardware available in the last what? five years?

As was pointed out earlier, other libraries like libevent/libev are also
not packaged with unbound, and might also be different versions compiled
with compile flags not ideal to you. Are you recompiling libevent manually
as well? Where do you draw the line?

ldns is not the unbound dns code. ldns is its own dns library used by many
other applications.
