I am trying to use an MPI build on my laptop, but I'm getting an error 
during configuration.

checking for crypt in library crypt... yes
checking for finite... yes
checking for isnan... yes
checking for isinf... yes
checking for mkstemp... yes
checking for va_copy... yes
Configuring with MPI
   MPI selected, but no known MPI method - what is "/usr/lib64/mpich2" ?

In my configuration (through SimFactory) I have this:
MPI          = CUSTOM
MPI_INC_DIRS = /usr/include/mpich2-x86_64
MPI_LIB_DIRS = /usr/lib64/mpich2/lib
MPI_LIBS     = mpich opa pthread rt

Cheers,
Steve
