The fortran front-ends have been merged. The two supported ways to link fortran are:
(1) Use mpifort / mpif77 / mpif90. mpifort preferred, or
(2) Use pkg-config mpi-fort --libs (recommended).

Don't rely on the names of the libraries provided as they may change across versions and architectures.
I've been submitting patches where necessary for this.
