I'd guess, something is wrong with your local environment problem. Try
first to get your system to compile the MPI hello-world program below.
As long as this does not work, your problem is definitely not DFTB+ related.

  Best regards,

program test_mpi
  use mpi
  implicit none


  integer :: size, rank, ierror

  call mpi_init(ierror)
  call mpi_comm_size(MPI_COMM_WORLD, size, ierror)
  call mpi_comm_rank(MPI_COMM_WORLD, rank, ierror)
  print *, 'node', rank, ': Hello world'
  call mpi_finalize(ierror)

end program test_mpi
