Fortran builds can be a little finicky - you have to set it up just right
for it to get the automatic dependencies right. Check out this thread:

In particular, for whatever reason, FORTRANPATH only picks up .f and .F
files. For .f90 and .F90, you need to set F90PATH. Furthermore, you need to
be sure to set them when the Environment is first created.
