@juhp I recreated this problem with just cabal. The recipe is:

cabal fetch alex
cd /tmp
tar xf ~/.cabal/packages/hackage.haskell.org/alex/3.2.0/alex-3.2.0.tar.gz
cd alex-3.2.0/
cabal sandbox init
cabal install --dependencies-only --enable-tests
cabal build
cabal test

which gets pretty much the same error as you see.

It looks like there are some files missing from the cabal file.
