How about this?

1. create a file system, say /usr/performer, on the host server --
   note: don't name it /usr/Performer
2. NFS mount that file system to all other machines
3. Create soft links between the directories on all the machines,
   including the server, to the separate Performer files and
   directories, e.g.,

   % ln -s /usr/performer/lib/libp*.a /usr/lib
   % ln -s /usr/performer/src /usr/Performer/src

I haven't tried this, tho we've done similar things with other file
systems. Potential problems:
- I'm not sure how this will interact with installing Performer.
  Obvioulsy, the links must be created before installing. So, that
  might mean if you've already installed Performer, you might have
  to uninstall it, create the links and new fs, then reinstall.
- This probably isn't possible if if your machines aren't running
  the same version of IRIX.
