Erlang with openssl using kerl on recent OS X (El Capitan, Sierra) with homebrew
Since I struggle with this every time I have to setup a new machine, here’s the best solution IMHO: https://github.com/kerl/kerl/issues/103#issuecomment-176704372
In short
$ cat ~/.kerlrc
KERL_CONFIGURE_OPTIONS="--with-ssl=/usr/local/opt/openssl"
CFLAGS="-DOPENSSL_NO_EC=1"
