[Rivet] rivet 2 on Mac OSX

[Andy Buckley]

Hi Hannes,

Looks like this is a FastJet bug in OS X Mavericks, which was fixed last
year. From http://fastjet.fr/all-releases.html:

29 October 2013: fastjet-3.0.6 (manual, doxygen, fjcore) is a minor
maintenance release. Main changes:
fixed compilation issues for two plugins using clang (clang-500.2.79,
Apple LLVM version 5.0 based on LLVM 3.3svn) under OS X 10.9 (Mavericks)

We hadn't updated the fastjet version in our bootstrap script, because
until recently LCG had not installed releases later than 3.0.3, but I've
done it now. Re-download the bootstrap and try again... hopefully it'll
work this time.

By the way, on Mavericks I think it is still necessary to set

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

before running the bootstrap script, due to an OS X clang/Python bug:
see http://stackoverflow.com/a/22322645/91808 if you want details.
Otherwise it will fail late in the build as it tries to build the Rivet
or YODA Python modules.

Cheers,
Andy
