[Rivet] Rivet 1.8.3b1 available for mcplots testing

[Andy Buckley]

Hi Anton,

We finally have that promised new version of Rivet 1.8.x for you to
test! A new 1.8.3b1 tarball is available as usual at
http://www.hepforge.org/downloads/rivet -- could you please try it out
and let us know if you seen any obvious problems? Thanks once again :)

Andy & co

PS. You asked about getting Alpgen working with PYTHIA6 in 64 builds of
AGILe. I've not seen the problem myself, but as we discussed if you can
send a stand-alone example that works and/or a stack trace, we'll try to
help with debugging / providing a fixed version.
