As of OS X 10.9 the BLAS Apple provided was known to have bugs. I only 
noticed any issue (If I remember correctly, "make test" failed) when 
configuring in single precision. However, this might be a reason to have 
petsc download BLAS/Lapack despite the libraries being available in 
Apple's framework.
