haskell.compiler.ghc902Binary: workaround com.apple.provenance xattr

  # calls install-strip ...

  dontBuild = true;

  # GHC tries to remove xattrs when installing to work around Gatekeeper

  # (see https://gitlab.haskell.org/ghc/ghc/-/issues/17418). This step normally

  # succeeds in nixpkgs because xattrs are not allowed in the store, but it

  # can fail when a file has the `com.apple.provenance` xattr, and it can’t be

  # modified (such as target of the symlink to `libiconv.dylib`).

  # The `com.apple.provenance` xattr is a new feature of macOS as of macOS 13.

  # See: https://eclecticlight.co/2023/03/13/ventura-has-changed-app-quarantine-with-a-new-xattr/

  makeFlags = lib.optionals stdenv.buildPlatform.isDarwin [ "XATTR=/does-not-exist" ];

  # Patch scripts to include runtime dependencies in $PATH.
