Dear Prof Ripley, 1. Ok. I will not use LAPACK from the Accelerate library.
2. Ok. It would be great, when the CRAN team has the time, to update the FAQ. 3. I need to pass -Wno-implicit-function-declaration to have the compiled R use the Accelerate BLAS. Without the flag (even without --with-lapack) R compiles fine but uses the included stock BLAS.
