I had a similar problem, but making sure that FastJet is cleanly built
with the right options, and that Rivet is fully linked against such an
installed FastJet made it work.

Did you build Fastjet with all plugins and all shared lib builds? You
should probably build FastJet 2.4.x with --enable-allcxxplugins
--enable-shared as args to configure. This may need to be a clean build,
since I had some trouble getting these options to propagate to the
nested SIScone configure in plugins/SISConePlugin/siscone.

These build specifics will have to go into our build instructions and
bootstrap scripts for 1.1.3.
