F77 is not sufficient to compile SIESTA, it needs F90 compiler. There is an option -Vaxlib in your arch.make that suggest you are using Intel compiler, not gfortran. Also MKL libraries suggest you are linking against Intel compiler versions. From what I see OpenMPI is build with ifort, but it is not installed in a system directory, so my suggestion from my first post holds: Check your PATH variable.
