@HaskellZhangSong and @yawaramin both encountered this. Can either of you follow these steps and report the results?
In shake/Build.hs, add the following print statement:
...
let confDir = packageConfDir rootDir
liftIO $ print confDir
..
and then run ./cleaninstall.sh and in the output should should get a file path. Go to that file path and share the contents of that directory.
