Indeed, I just find out on Google that there is no tar.gz file. However, I have downloaded a .zip file that should contain everything about WOLFPSort from GitHub and loaded into EffectorP, following the READ.ME.txt file. Because of some errors, I could not make it run yet.
Not being an informatician makes it very difficult to modify the code as you suggested. That's why I was looking into way to make EffHunter run as it is described on GitHub.
