Yes.

You would have rebuild all the resolver libraries and any utils/programs
that use them (well, if they are linked statically at least - if you dont
know what that means then dont do it). This is not a simple task and
probably overkill for what you want to do.

Why not ask you network administrators to allow port 53 UDP traffic
to/from your host? Or ask them if they have internal DNS servers that you
can use in /etc/resolv.conf (yes that *is* the right file) instead?

Seems silly to mess with header files and rebuilding chunks of the OS
when a better alternative may exist.
