Perhaps your link line is wrong. Let's start with a PETSc example. Can you
make Vec ex1f90/F90?

  cd $PETSC_DIR
  cd src/vec/vec/tutorials/
  make ex1f90

That will also show the correct link line.

  Thanks,

     Matt

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
