[Rivet] Python, Rivet 1.20, CERN AFS, LXBATCH

[Andy Buckley]

Ah, that's probably because SLC5 is a complete mess when it comes to
compilers, libraries, etc.: the LCG libraries like HepMC, Fastjet, etc.
are all built with compilers other than the ones that are available as
standard on the SLC5 system! (I did mention that this seemed a bit dumb
about a year ago, but the lxplus team didn't see the problem!)

So when using lxplus5 you should first source the setup for a useful LCG
compiler, e.g.

. /afs/cern.ch/sw/lcg/contrib/gcc/4.3/x86_64-slc5-gcc43-opt/setup.sh

This is what I did when testing Rivet 1.2.0 pre-release copies on
lxplus5, and they worked fine. I guess this should be added to the Rivet
wiki!
