Hmm, I'm not sure about this. Interestingly, it works if I use 

    "$(mkoctfile -p BLAS_LIBS)"

in my developer makefiles alone. As soon as I add

    "$(mkoctfile -p BLAS_LIBS)" \
    "$(mkoctfile -p LAPACK_LIBS)"

I get errors. Note that linking to BLAS alone just works when I use Accelerate. 
The reason is that Accelerate also includes the LAPACK stuff which my code 
needs. Obviously, I have to link to both BLAS and LAPACK on non-mac platforms.
