Ahhh, this is an old distribution from the 27 series, likely 27bz-9 or
27cz-9.

Hmmm, if this is the low-cost basic edition (with "bz" in the part
number), it did not ship with the PVFS file system libraries.

The basic editions were intended as a minimal complexity, plug-and-go
deployment platform.
The PVFS (Parallel Virtual File System) implementation requires specific
configuration to match the cluster configuration and application usage.
Thus we provided the precompiled PVFS libraries with the professional
and supported developer's releases, but not the basic/deployment releases.

The solution is to   -lpvfs   from the compile line.
