[Rivet] HepMV version issue

[David Grellscheid]

Hi James,

a given Rivet version is built with a given HepMC version, and is linked 
to it. I suspect that your version of Rivet is linked to the outdated 
HepMC 2.03.

Please find a Rivet that has been compiled against the modern HepMC 
2.06, which will read HepMC files from any version just fine.

The older HepMC 2.03 cannot read newer versions of HepMC files. It lacks 
crystal ball support.

Hope that helps,

   David
