[Switching to thread 11523]

Answer 1

I've been running into this same issue lately when compiling an app in Xcode 4.2, so I searched for this same issue in the apple developer forums, and I found many threads specifically about this dns.so warning, and in many of these threads, Apple engineers replied and said it's ok to ignore this warning when it involves dns.so. One of them stated it would not even be used on iOS, so it can be ignored.
