[Rivet] Minor bug in rivet-bootstrap [Re: Rivet 1.5.0 released]

[Ben Waugh]

The Rivet C++ libraries are in .../lib. The only thing in lib64 is 
python2.4/site-packages/.

By the way, you have an account "buckley" on our cluster so feel free to 
log in and see if it works for you. Can't see anything I could have 
meddled with in my environment to screw this up, but...

Cheers,
Ben
