I think this indicates that the HDF5 library with which you have linked 
FLASH has not been built with parallel support - although it is surprising 
that you did not already get an error at link time (i.e., in the last 
stage of running 'make').

There may be additional sources of problems if you are running flash4 in a 
different environment from that in which it was built - in particular, if 
you are running under a batch system - relating to locations of 
dynamically linked libraries, LD_LIBRARY_PATH, etc.

This is hard to impossible to diagnose remotely without access to the 
system.
