Comment (by lockhart):

 You are on a very old version of MacOS (10.6). On my somewhat-old 10.13,
 the preferred compiler is clang in /usr/bin/clang and openjade compiles
 just fine.
 Would you like to develop a patch which might work on your older machine?
 I'd suggest trying to pass a --std=C++03 on the compiler command line.
 I'm happy to give you some more details if needed.
