[Rivet] poblems installing rivet on mac

[Hannes Jung]

Dear Hendrik

thanks a lot for your reply.
I guess it was just the way how to define the AGILE_GEN_PATH 
which I was missing. 
Following your instructions lead to:
-------
~/jung/cvs/rivet/tmp> export AGILE_GEN_PATH=/Users/jung/jung/cvs/rivet/gensertest    
~/jung/cvs/rivet/tmp> agile-runmc --list-gens                                    
Pythia6:424
~/jung/cvs/rivet/tmp> agile-runmc Pythia6:424 -P lhc7000.params -n 10 -o events.hepmc
Generating 10 events
Generator is Pythia6:424
terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
zsh: abort      agile-runmc Pythia6:424 -P lhc7000.params -n 10 -o events.hepmc
~/jung/cvs/rivet/tmp> 
-------

at least the generator is found.... now I have to find, why pythia is not working,
but that is a different issue.

Thanks a lot
cheers
Hannes
