Hi Bryan,

Sorry that we never got back to you on this... I suspect that none of us 
really knew what to suggest! I did hear someone else mention something 
about odd linker errors with HepMC, and that it was solved with the 
alpha version of Rivet 1.5.1. I don't know what we did -- nothing on 
purpose, I think -- but now that 1.5.1 is officially released you could 
try that. Good luck, and let us know if there are still problems: we'll 
try to be more responsive this time!

Andy
