Thank you for your response. In the end, I made it work. I think that the problem came from the "cyclic" dependencies between MPICH2 and PVFS2 when configuring/building/installing them.
If anyone is interested, I ended up using orangefs-2.8.6 and mpich2-1.4.1. However, IOR can only be used with MPIIO, since I guess that the kernel interface is needed for POSIX.
