[Rivet] Compilation problem on Mac OSX 10.11 with Clang 3.7

[Andy Buckley]

Hi Peter,

Check the release announcement for Rivet 2.4.2 -- it is primarily 
intended for use with YODA 1.5.x.

YODA 1.6.x uses C++11 features, which usually need to be enabled by 
passing a -std=c++11 flag to the compiler. (I think it will become 
default in GCC 6.x; not sure about clang/LLVM's plans).

YODA 1.6.1 won't break Rivet 2.4.x, but you will need to explicitly pass 
that C++11 mode flag in the CXXFLAGS environment variable or similar. 
Otherwise you'll get errors like this about features that didn't exist 
in the earlier standard. Rivet 2.5.0 onwards will itself use C++11 and 
so the necessary flags (if any) will be automatically present. I hope we 
can turn the current beta series into a proper release before too long.

Cheers,
Andy
