Hi LoyceV,
Yup, you were right, you had to keep the top line, the bottom one is no longer needed.
It might be best to just use the container, i have it running on a demo machine and it works just fine... But if you want to try to build it on your local machine, you're always welcome to shoot me a quick PM (local language is fine, doesn't have to be in English)
I'm currently figuring out if i can build some kind of cpuminer in the same container and get it to work properly... cpumining might be long dead, it should still be feasible for testnet4.
