Installing Erlang with Kerl

On Redhat-type boxes, install the dependencies with a package manager.

yum install gcc gcc-c++ glibc-devel make ncurses-devel\
    openssl-devel autoconf java-1.8.0-openjdk-devel git readline-devel\
    libyaml-devel libxslt-devel libffi-devel libtool unixODBC-devel\
    unzip curl wget which less gnutls procps fop -y

Pull down the kerl entrypoint, make it executable, and move it to a bin directory.

curl -O https://raw.githubusercontent.com/kerl/kerl/master/kerl
chmod a+x kerl
mv kerl /usr/local/bin/kerl

kerl build 23.3.3
kerl install 23.3.3 /opt/erl-23.3.3/
