What I meant is that if one doesn't know this and resolves the blacs names
needed by scalapack by just linking against libmkl_blacs_lp64.a (which is
legitimate), then he or she could have such problem, because the
MKLMPI_Get_wrappers symbol is apparently not needed (just searched for by
using libdl calls).
