James, can you hack the bootstrap script to make AGILe find Herwig++ and
Pythia 8 on AFS? It would be good to have them available, since both now
work!

(I've copied the Genser developers in on this)

Hmm, the 2.3.9 release was specifically to fix problems with IO_HERWIG:
is this behaviour expected?

Yes that's what I get. I also get strange behaviour with the
(unreleased) Genser bootstrap version of Pythia 6, but building the same
generator with AGILe's mkGenserArea script works! I've not tried a
stand-alone run with HepMC 2.3.9, though.

Genser people, any comments?
