My understanding is that the Scalable Informatics mpiBLAST RPMs have 
been compiled against mpich, whereas you are using LAM/MPI.  mpiblast is 
calling mpich's MPI_Init and LAM never gets an MPI_Init call, leading to 
the above error.  Either switch to mpich or rebuild mpiBLAST on your 
system with LAM.
