The symbol itself is only in the .so files, not in any of
the object modules, so it looks like it's something being
pulled in as a link-time dependency by libtool/ld.
$ grep -R res_query .
Binary file ./src/.libs/libhwloc.so.0.0.0 matches
Binary file ./src/.libs/libhwloc.so matches

I *suspect* it's being pulled in by libpci - here:
$ nm /usr/lib/libpci.a | grep res_query
U __res_query
$ rpm -qf /usr/lib/libpci.a
pciutils-devel-3.1.7-3.el5
Oddly that's listed as being in the library on Ubuntu 11.04
too, but it's not ending up in the libhwloc.so on that platform.
cheers!
