This is definitely the issue. OSX ships with a version of BLAS/Lapack... it's called Veclib and it's one of the "Frameworks" on OSX. It can be used by Petsc (and libMesh)... but last time I tried I seem to remember that I had to specify extra libraries to be linked into Petsc so that they would get picked up by libMesh. I recommend using the--download-c-blas-lapack=1 option when configuring Petsc. This way you get a much more standard version of BLAS/Lapack and everything should work.
