On Linux this is usually prevented by a correct rpath. According to http://www.cmake.org/Wiki/CMake_RPATH_handling, Mac OS X has @rpath, @loader_path and @executable_path mechanism. I don't know anything about that, but could it be that the rpath settings are not correct for Darwin?
Also I think we should go ahead an increase the so version now or create a separate bug with a todo list for the release so that this isn't forgotten.
