Correct, it does not. It needs to be taught. I believe that just
"-undefined dynamic_lookup" is necessary; "-framework Python" is
redundant since it will be available to the dynamic_lookup as soon as
the extension module is loaded.

And the hard-coding of Accelerate is my fault, oh so many years ago.
