Comment (by bmundim):

 Hi Erik,

 thanks for the explanation. There is still an issue
 with machines (I have in mind supermuc) with no standard
 MPI directory installations. I recall a conversation with
 Ian where he convinced me that MPI_INC_DIRS and MPI_LIB_DIRS
 should be set independently from MPI_DIR, and MPI_DIR set
 to NO_BUILD to prevent the thorn from building it. Your suggestion
 of setting MPI_DIR to /cm/shared/apps/mvapich2/intel-14.0.3/2.0
 might work on Loewe, but will probably fail on Supermuc,
 which has a non-standard MPI installation. In any case,
 let me see if it does solve for Loewe first.

 Thanks,
 Bruno.
