Hmmm. I always install using some advanced BLAS: On Windows, e.g., simply using the Rblas.dll provided by Brian Ripley, on Linux it's really no effort to compile it yourself.

For huge matrices you can use your some-years-old-desktop machine (with some advanced BLAS) to outperform expensive multi-CPU machines (without advanced BLAS).
