I’m not sure if I understand the problem. I believe bootstrap.sh should be expected to be run only on a bare system with nothing but GHC installed. If the user is already able to install Cabal packages, i.e. has some version cabal-install, they should be using that, not bootstrap.sh. Does this assumption simplify the problem you’re seeing?
