Are you sure there's a -release tag?

where you trying to do for the initial clone?
I would use
Git clone -b ghc-7.8.3 ghcUrl ; ./sync-all get I think.
Point being the clone process is different.
I was on the ghc-7.8.3-release git tag and updated the submodules, so I was on the right commit I think. Does 'sync-all get' check out the correct commits or at least branches? I think that's the part that what went wrong.
