Hi Ron, Apple keep moving the goal posts on their platform so it's a case of keep trying to catch up with whatever the new flavour of the month is. In OSG svn/trunk I have checked in a submissions that allows one toggle which libs to link against, look out for the OSG_CXX_LANGUAGE_STANDARD option, set it to either C++98 or C++11.
