- just playing around, builds OK on amd64, but JIT requires FreeBSD src patch for arm64
- needs src tarball from freefall:/home/dch/public_distfiles/erlang-otp-25.0rc2_GH0.tar.gz or https://people.freebsd.org/~dch/tmp/erlang-otp-25.0rc2_GH0.tar.gz in your distfiles cache
- TLDR use CURRENT or 13.1-RC2 for arm64 jit goodness
