Title: Upadate formulae r with optimized blas

Please correct me if I am wrong. Without the veclib option, r will be complied with the netlib reference implementation of blas. At least this is what happened in my machine. The only downside of veclib is that with some old version Xcode, I cannot recall the exact version, on certain Mac pro, which I cannot recall the exact version of their CPU either, it will run in serial mode and cannot detect the correct number of cores. But it is no worse than the reference implementation. veclib come with all Xcode under the umberalla framework accelerate. So I really don't see the point of not using it. I found the same problem with other formulas, e.g. Jags. If someone can test it on more machines to confirm my patch is a sensible thing to do, I will be happy to patch other packages using blas, too
