Hi,
Does `git clean -fdx .` in libraries/Cabal help? git clean doesn't go into
submodules.

Hi all,
I've finished quite a big rebase and was trying to rebuild, but it failed with:
ghc-cabal: Encountered missing dependencies: Cabal ==2.5.*
I then tried applying my patch on a fresh checkout of GHC and found the reason:
*libraries/Cabal/Cabal/Distribution/Compat/Prelude.hs:119:1:**error:*
* Bad interface file: libraries/Cabal/Cabal/dist-boot/build/Distribution/Compat/Binary.hi*
* Something is amiss; requested module Cabal-2.4.0.1:Distribution.Compat.Binary differs from name found in the interface file Cabal-2.5.0.0:Distribution.Compat.Binary (if these names look the same, try again with -dppr-debug)*

*141 |**import Distribution.Compat.Stack*
* |** ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^*
I'm sure I did `git module update`; I even `git clean` everything and `make` from fresh but somehow the cabal still isn't updated. Can anyone help me on why this is happening and how to fix it?
Thanks so much,
