Error while running cabal v2-install --overwrite-policy=always --install-method=copy --installdir=inplace/bin

ghc/compiler/prelude/PrimOp.hs:96:1: error:
    parse error (possibly incorrect indentation or mismatched brackets)

cabal: Failed to build ghcjs-8.10.7 (which is required by exe:haddock from
ghcjs-8.10.7, exe:ghcjs-pkg from ghcjs-8.10.7 and others). See the build log
above for details.

steps to reporduce

 git clone https://github.com/ghcjs/ghcjs.git
 cd ghcjs
 git submodule update --init --recursive


ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.10.7

cabal configure -w $(which ghc)

cabal v2-install --overwrite-policy=always --install-method=copy --installdir=inplace/bin
# here the error rises

expected behaviour

just to have my ghcjs compiler...

useful infromations

looking inside ghc/compiler/prelude/PrimOp.hs
the following code is present

allThePrimOps :: [PrimOp]
allThePrimOps =
#include "primop-list.hs-incl"

tagToEnumKey :: Unique
tagToEnumKey = mkPrimOpIdUnique (primOpTag TagToEnumOp)

also opening the file in vscode shows the following error
