There are other issues with using prefix installs of PETSc. It turns out that there are links back to the source directory where you build PETSc for any external libraries you use. At least this is the case with the newest version of PETSc 2.X. You will see this if you delete the source directories after installing PETSc in the prefix path. While this really doesn't have anything to do with whether or not the existing m4 script is correct, I just wanted to caution anyone doing prefix installs to be aware of that issue.
