I notice that this message also appears with 1.8.4 (in both cases, when
cross-compiling for linux-arm). However, for some reason, with 1.9 the
extconf process aborts after printing these lines to mkmf.log. But with
1.8.4, extconf continues, prints more messages to mkmf.log, and
eventually produces a good socket.so. Is there something different about
extmk.rb or mkmf.rb in 1.9 that could be causing this?
