[Rivet] Problems with Rivet 2.4.0 on OS X Mavericks

[Andy Buckley]

Thanks Alexander,

That's strange -- for sure, mixing and matching LLVM/Clang with GCC 
would cause problems but it's unexpected that a pure Clang setup would 
somehow miss a symbol. We'll keep a look-out for this issue as we 
continue to develop, but glad that you found a work-around.
