+NOTE: due to directory layout at this cluster in combination with Spack compiler wrappers, using `intel-mkl` is not possible here, see [this comment for details](https://github.com/spack/spack/issues/8324#issuecomment-393418311).
 Finally install dealii 
 ```
-spack install dealii%intel~assimp~gmsh~petsc~slepc+mpi^intel-mpi^intel-mkl
+spack install dealii%intel~assimp~gmsh~petsc~slepc+mpi^intel-mpi^openblas
 ```
-Note that `%intel` specified the compiler whereas `^intel-mpi` and `^intel-mkl` specified which implementation of MPI and BLAS/LAPACK we want to use. Here we also disabled `assimp` and `gmsh` as they do not build with `Intel`.
