Are you by any chance on a non-'master' branch of GHC? This happened to me when I ran `./sync-all pull` when on a local branch. There may be a simpler fix, but this is what worked for me:

1. `git checkout master`
2. `./sync-all pull`
3. `git checkout local_branch`
4. `git rebase master`

The goal is to run `./sync-all pull` on the master branch and then to rebase your local branch against it. This should update the submodule metadata in your local branch.

Afraid not. I'd tried "git submodule update".  The command you give is a no-op; libraries/Cabal is stuck on commit 14c5a3f; and that's what git submodule status says it should be.  But it shouldn't!

|
| git submodule update libraries/Cabal/
