Yes and No(?). In x86_64, there is a symlink

libRblas.dylib -> ../libRblas.dylib, and in ..: libRblas.dylib ->
libatlas-MacPro.dylib

And similarly in i386 and ppc. Shouldn't that work like your suggestion b)?
It doesn't.

ln -sfn ../libatlas-MacPro.dylib libRblas.dylib

I would prefer this to a) since it avoids switching back and forth; I don't
care about moving binaries.

Thanks for your help,
