[Rivet] HepMC static

[James Monk]

Hi Lars,

It did not produce shared libraries with my version of gcc because  
that requires an extra compiler option to produce dynamic libraries  
with undefined symbols (-undefined dynamic_lookup).  Lynn has now  
committed my suggested fix to the HepMC repository and has promised a  
release with this in "by the end of the week."

I guess Jon is right and we don't need to redistribute the HepMC  
release, although it is convenient to be able to get everything from  
one place.

James
