Thanks Brandon, I checked the strace log and before the error is written, there's a log entry:
openat(AT_FDCWD, "_build/stage1/libraries/ghc-prim/build/GHC/Types.hi", O_RDONLY|O_NOCTTY|O_NONBLOCK) = -1 ENOENT (No such file or directory) So it looks like GHC is indeed looking at the correct hi path, not the doubled path.
