[Rivet] Python, Rivet 1.20, CERN AFS, LXBATCH

[Ben Waugh]

Dear Terrance,

I had the same problem ("invalid conversion" in one of the source files 
generated by Swig) compiling Rivet on SLC5. There is a bug in the 
version of swig supplied with the OS, so I had to install my own version 
(swig-1.3.40) locally and place it in my $PATH before the standard bin 
directories.

Cheers,
Ben
