Thanks for the suggestions. We tried this today and things seem to be
working OK. We need to to more testing, but we will proceed to setup out
LInux systems this way as we transition them all to Performer 3.2

I would still like to hear something on this topic from SGI.

If you extract these libraries (e.g. from the tgz package performer_eoe-3.1.1_gcc3-0.tgz) and copy them in /usr/lib (or in your application directory), there will be no problem to run binaries for both versions.
