Yes, my Xcode is up to date. Have you tried rebuilding FFTW since upgrading? I hadn't until now, and it wouldn't build without getting rid of the `--enable-avx` flag. Ideally, autoconf should detect this, but it doesn't seem to, which is annoying.

The OpenBLAS thing has been an issue for a while and I filed [an issue](https://github.com/xianyi/OpenBLAS/issues/68), but it hasn't been fixed yet although the patch is trivial. I just created a [pull request](https://github.com/xianyi/OpenBLAS/pull/76) to fix it. Hopefully it will get into the 0.1 stable release. Even once it does, this perl hack won't do any harm.

The Fortran business is so that our binaries will actually work without needing gfortran installed on the target system. This was keeping our binaries from working for people. Maybe this isn't the best way to do it since it adds overhead to all of the dynamic libraries that have Fortran code, but I suspect that the overhead is pretty damned small.
