Well, that depends on what the source of your RRs is.
I've used ldns_rr_new_frm_str() before (not the _internal variant):
ldns_rdf *origin = ldns_dname_new_frm_str(origin_str);
ldns_rr_new_frm_str(&rr, rr_str, ttl, origin, NULL);
(where "origin_str" is $ORIGIN and "rr_str" is the RR in the form "@ RTYPE RDATA")
Alternatively, it's possible (but tedious) to create it one field at a time:
ldns_rr *rr = ldns_rr_new();
ldns_rdf *owner = ldns_dname_new_frm_str(owner_str);
[not sure how to set the RDATA yet, the _frm_str method is probably easier in many cases, but this method is probably faster if you have the RDATA already in wire format instead of ASCII].
