Yes, a bit hard to debug with this information! It looks to me like it's
likely to be a 32 bit/64 bit issue... maybe the version of Python in
your path is 32 bit and it's trying to load 64 bit built libraries or
similar.

Running "rivet --help --verbose" might (should) give a more complete
debug printout: I suspect that the "user friendly" message about
requiring the "rivet" module is hiding an attempt to load that module
which fails because either the _rivet module library, or one of the
libraries it chains to, is the wrong architecture. We try to get these
things right (e.g. prepending to the LD_LIBRARY_PATH in rivetenv.sh) but
it's not 100% foolproof!

Hope that helps: with more debug printout we can maybe get a bit further.

Cheers,
Andy
