[Rivet] Rivet 2.5.1 segfault on debian jessie

[Andy Buckley]

Not sure what exactly went wrong for you, but my guess is that a 
Rivet*.so file from the old version was left in place somehow. And since 
it wasn't rebuilt with the new API, etc. its contents segfaulted on 
being dlopen()d / run.

Best to install into a completely fresh area if possible, but a manual 
clear-out of Rivet*.so and .info etc. files from $prefix/lib and 
$prefix/share/Rivet is a good plan, as is removing the rivet directory 
and any .egg files in the $prefix/lib*/python*/site-packages
