To run Performer 3.1.x applications, you need libpf*.so.4. Performer 3.2 installs libpf*.so.5. 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.

So, either copy libpf*.so.5 from the 3.2 packages over a 3.1.x installation, or install 3.2 cleanly and add libpf*.so.4 libraries. Both should work.

I don't know if there are any licensing issue with this, though...
