Hi,
Using Cabal 1.4 Branch and Cabal-install HEAD:
C:\Neil\uniplate>cabal install --hugs Resolving dependencies...
Should work now. Also "cabal install --hugs whatever" should also work. It assumes that all deps of "whatever" are already installed. It can still go wrong. Suppose foo build-depends on bar < 2 but bar-2.0 is available, then: $ cabal install foo bar will will (probably) succeed, however it will pick bar-2.0 because it's the latest available, even though foo cannot work with bar-2.0. Perhaps there is in fact a way of working out what hugs packages are installed. Each package that comes with hugs (2006.9 at least) has a Paths_pkgname.hs module and it defines: version = Version [...] [] So it would be possible to parse this to get the versions of all installed packages.
