I'm a linux guy so take the advice with a grain of salt... When you
run the configure script, look at the output at the end of the run, it
should either say

Options enabled:           shared BLAS, ...   (means you are using R BLAS)

or it should mention OpenBLAS in External libraries (meaning you are
using OpenBLAS).

You can also see the results in config.log of you search for BLAS.

Or you could use the old trick of replacing libRblas.dylib with a link
to the appropriate OpenBLAS dylib.
