Actually I didn't get lots of emails about this... you're the first.
Yes, I was surprised too!

Yes, that's right! That area was never meant for production use -- the
hint is in the "experimental" bit of the path! The version in there was
a pre-release version from about 2 years ago; and was subject to change
at any time (I'll use it again if I ever need to make a slightly public
pre-release copy available for testing.)

I just added a README file to that directory explaining how to set up a
reliable existing AFS Rivet build, but here's the short version:

setupATLAS
localSetupPython 2.7.3-x86_64-slc6-gcc47
source
/afs/cern.ch/sw/lcg/external/MCGenerators_lcgcmt67c/rivet/2.2.0/x86_64-slc6-gcc47-opt/rivetenv.sh

Hmm, that's odd. How does it go wrong, and with what release(s)?
