libRivet.so is in a directory pointed to by the LD_LIBRARY_PATH  
environment variable. It was my understanding that this was how users  
were supposed to add routines themselves (using these pluggable  
analyses) so I installed Rivet etc on a CDF machine so that people  
can easily do that. Someone should correct me if I'm wrong here!

It works with a standard analysis run on its own but fails if I try  
to run them both.

I'm building it on a CDF cluster machine (do you want more details of  
the machine?)

Cheers,
Emily.
