[Rivet] RIVET setup for lxplus7

[James Howarth]

Hi Andy,

I tired that first and it didn’t work. Please keep some support for us techno-idiots who can’t handle the wide variety of architectures out there (a.k.a. mac users :D)

I forgot to say as well, the smearing functions work fine in this version (or at least I get sensible numbers). I’ll send an email to Ynyr shortly to confirm.

Cheers,

Jay
