Thank you ! I have fixed the script to fit John's future versions.

Another approach using latest trunk:

sudo yum install -y openssl-devel
sudo yum -y group install "Development Tools"
cd ~
git clone --depth=1 https://github.com/openwall/john
cd john/src
./configure
make -j

mkdir ~/target && cd ~/target
curl -LO https://filebin.net/****/target.7z
