 The undefined symbols are in /usr/lib/libresolv.dylib but -lresolv
 is not included in link command.  Looks like configure fails to
 properly recognize the need of it (it finds res_query in
 /usr/lib/libc.dylib and assumes the rest are there as well -- test for
 functions in -lresolv is never performed).
