This might have something to do with multiple libiiwusynth.so files
installed. I don't recall if the library versions changed in 0.2.2 or
not (was changed to libiiwusynth.so.1.0.0 from libiiwusynth.so.0.0.0).
ldd can help in these situations. If you do an "ldd iiwusynth" you will
get a list of the dynamic libraries and their locations. Hope that
helps.
