It certainly counts. You have several which mean you need to be very careful about the MPI you are picking up during compilation versus the one you are using at runtime. You might consider using a "modules" management system where you have exactly one loaded in your PATH, compile paths, link paths at once. Otherwise it's a free for all and subtle changes in the search order can lead to results like this
