Is there any way to specify what nameservers will be used when a call to
gethostbyname is called? This must be done from within the code, not by
modifying /etc/resolv.conf.

I'm about to tear into the source code for dig and I would much rather avoid
that if possible

You don't say what kind of system you're using, but programs can
usually tweak the resolver's behavior by calling res_init() and
then modifying the global _res structure before calling any resolver
functions like gethostbyname().  _res is a struct __res_state, which
should be defined in <resolv.h>.  The number of nameservers and
their IP addresses are in the nscount and nsaddr_list fields.
