[Rivet] HepMV version issue

[Frank Siegert]

Hi James,

I think this might be due to the 2.06.05 event file containing
additional lines which make HepMC 2.03.11 fail. I thought this was
fixed in 2.03.10, but seems like not.

Would it be an option for you, to use HepMC 2.06.05 in your setup,
i.e. use the following AFS location?
/afs/cern.ch/sw/lcg/external/MCGenerators_hepmc2.06.05/

Cheers,
Frank
