Just for the records:

I have an installation using the MKL distribution of scalapack but it doesn't use IntelMPI

I don't understand your comment. MKL ScaLAPACK is build against Intel MPI, Open-MPI and (maybe) SGI MPT.

Because of MPICH ABI compatibility (https://www.mpich.org/abi/), you should be able to use the MKL ScaLAPACK libraries compiled against Intel MPI with MPICH, MVAPICH2, Cray MPI and any other late-model MPICH derivative, so long as the binary representation of MPICH objects does not change (e.g. MPI_Status object).

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).
