[Rivet] Herwig 6.510 and AGILe HepMC issues

[David Bjergaard]

I'm a little confused about your HepMC question.  I installed rivet+AGILe
with the bootstrap script on the hepforge page. It looks like the
version it used was 2.06.05:
> $ ls /home/dave/rivet/build/
> agile  AGILe-1.4.0  fastjet-3.0.3  HepMC-2.06.05  rivet  Rivet-1.8.1


AGILe works fine when I use Fortran Pythia (Pythia6:423). Would AGILe
have been installed before HepMC? I have some notes on what I had to do
to install rivet, but I don't recall manually installing HepMC. Can I
force AGILe to recompile itself and see if it goes away?
