Maybe you do not have open inventor installed?

What does ldd say about your .so file?

I get:

         libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb6d31000)

Note that I built libpfiv.so from source, because it still,
(after reporting this bug 3 times in 3 years or so), contains
a bug that caused opaque geometry to be sorted in transparent
bins. Transparency from iv models are often messed up big time
in performer.

That said, I believe the sgi-supplied libpfiv did load for me.
