No. Look closer. The symbol rfc1035_default_resolver is also referenced from 
testlookup.o, which gets linked directly against the static library. It 
should pull in that module just for that reason alone.

This is apparently some oddball behavior of BSD lineage ranlib. ranlib 
indexes only function symbols in static library members, and does not index 
the non-function symbols. The result is that the linker searches static 
libraries for unresolved function symbols only. If a module does not define 
any function symbols, but contains only data symbols, the linker ignores it.

Refreshing my memory with a little Googling, it seems that you need to set 
RANLIB="ranlib -c" in the environment, prior to running the configure 
script.
