Dear Andrew, this should work on XC-40 with quantum-espresso-5.4.0.
Here I used intel environment: module swap PrgEnv-cray PrgEnv-intel and scalapack.
Generally, on CRAY machines you need to use ftn for fortran and cc for C.
Those are wrappers that call the environment compiler (pgi,cray,intel or
gnu)
under the hood.

Let me know if you experience any problems.

Nicola
