Hi
Both errors are a consequence of the fact that we do not know what packages are installed for hugs. It is printing all the packages that it thinks are missing, that is... none.
For cabal-install, I can accept this. But from what you are saying cabal seems to have recently become broken so that it just won't work with Hugs at all? That is a real shame.
For a future hugs release it would be enormously helpful if it would include the InstalledPackageInfo files for all the bundled packages and if there was a way of discovering what directory to look in to find these packages. Then we could build a proper index of the installed packages as we do for ghc. Also we need a hugs --version flag so Cabal can actually figure out the hugs version so it knows whether it supports an installed package database. Currently hugs is almost unversioned (check System.Info.compilerVersion).
File suffient bugs (http://hackage.haskell.org/trac/hugs) and hopefully they will get fixed. Thanks Neil
