Maybe order matters? not sure....

build_commands

My handwritten command (that works):

xcrun --sdk macosx10.8 clang++ @all_objs -o bin/lib/macosx/gameplay.ndll -dynamiclib -fpic -fPIC -m32 -fvisibility=hidden -L. -L../../../GamePlay/external-deps/bullet/lib/macosx -L../../../GamePlay/external-deps/lua/lib/macosx -L../../../GamePlay/external-deps/libpng/lib/macosx -L../../../GamePlay/external-deps/oggvorbis/lib/macosx -logg -lvorbis -llua -lbullet -lgameplay -framework IOKit -framework Cocoa -framework OpenGL -framework Quartz -lz -lpng -lvorbisfile -framework OpenAL -lvorbisenc

What Build.xml produces (and fails):
