Install sysadmin on Amazon Linux?

Hello all,
trying to install sysadmin on my freepbx system that runs on Amazon EC2:

~  sudo yum install sysadmin
Loaded plugins: priorities, update-motd, upgrade-helper
No package sysadmin available.
Error: Nothing to do
~  cat /etc/os-release
NAME="Amazon Linux AMI"
VERSION="2015.09"
ID="amzn"
ID_LIKE="rhel fedora"
VERSION_ID="2015.09"
PRETTY_NAME="Amazon Linux AMI 2015.09"
ANSI_COLOR="0;33"
CPE_NAME="cpe:/o:amazon:linux:2015.09:ga"
HOME_URL="http://aws.amazon.com/amazon-linux-ami/"

Does anyone know how to install sysadmin on this platform?

Thanks
