Without seeing the code, it sounds like Tim might be right: someone is trying to re-define the MPI_STATUS_SIZE parameter that is being defined by OMPI's mpif-config.h header file. Regardless of include file/initialization ordering (i.e., regardless of whether mpif-config.h is the first or Nth entity to try to set this parameter), user code should never set this parameter value.
Or any symbol that begins with MPI_, for that matter. The entire "MPI_" namespace is reserved for MPI.
