... because it has nothing to do with R itself. It was merely a packaging bonus that inadvertently disappeared as we switched OS on the build machine. You can still do it yourself - either by copying the vecLib.dylib from the previous version or by symlinking the Accelerate framework. I'll see if I can restored it going forward.
