Well, I'd love to know command/option to put in named.boot. However, I suspected that at first so built the resolver from stable (which I assume was 2.1.5). Since I didn't have the problem in 2.1.5 I figured running its resolver would be the cure. It wasn't. Same effect. However, building host, or traceroute, or netstat with libc.so.2.2 and libresolv.so did fix the problem. I don't believe this is a named problem. However, now that I think of it... I was running the 2.1.5 named when I rebuilt host/traceroute and tested them. Perhaps both have to be changed. I'm not sure and can't test it at the moment. Changing named itself isn't sufficient though.
