The Apple Clang v8.1.0.8020042 is finally able to compile DUNE. However, compiling the DORiE executable still doesn't work due to errors in the std::shared_ptr implementation.

Here is a backtrace:

/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/memory:3798:7: error: exception specification of overriding function is more
      lax than base version

If this can be fixed, we could support compiling DORiE with the default Apple Clang.
