The contents of the petsc.pc file are listed below. It looks good to me. The
Libs.private variable seems to include the -lf2clapack and -lf2cblas libraries.
I don't know how this info gets propagated up the build chain.

The PETSc library I’m linking to (v3.16.3) was configured with
-download-f2cblaslapack so it should have these libraries, but when I try and
link one of the test applications in GridPACK I get the errors

they had viable blas and lapack libraries in their path and I don’t. Is there
anything special you need to do to make sure that the build is pointed at the
libraries that get created with the -download-f2cblaslapack option?
