[Rivet] difficulties with compiling Rivet on Mac

Hi Jong Soo,

Thus spake Jong Soo Kim (jongsoo.kim at adelaide.edu.au):

This is a problem in Rivet 1.8.2. You can try our 1.8.3 release
candidate (http://www.hepforge.org/archive/rivet/Rivet-1.8.3b1.tar.gz).
Or apply these two patches:
http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/COMP/CMSDIST/rivet-1.8.2-fix-duplicate-symbols.patch?revision=1.1
http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/COMP/CMSDIST/rivet-1.8.2-fix-isnan.patch?revision=1.1

Cheers,

    Hendrik
