After checking your terminal window, you are doing wrong: it's not in "/Library/ssdtPRGen" you need to place files and execute commands, but in "~/Library/ssdtPRGen" (= "/Users/<yourusername>/Library/ssdtPRGen").
So:
1) Delete the ssdtPRGen folder in "/Library/".
2) Delete the ssdtPRGen folder in "~/Library/".
3) Work ONLY in the "~/Library/ssdtPRGen" folder.
4) Follow EXACTLY all the steps in my post #134 (unzip attached file in "~/Library/", and follow the steps).
5) If there is still an issue, capture all commands and reply to this message. Also, go in "~/Library/ssdtPRGen/data" and capture the output of the command "ls -a -l".
