  In Performer 1.2 for IRIX 4.0.5, libpr is platform- specific with one
  of two versions installed depending on whether the machines is a
  RealityEngine or not.  Binaries linked on non-RealityEngine machines
  will run on a RealityEngine, but not all features will be available.

  Performer 1.2 for IRIX 5.2 contains a single version of libpr for all
  machines.  Applications built with Performer 1.2 for Irix 5.2 are
  fully compatible across machines and can run on any Irix 5.2 machine
  without relinking.
