[Haskell-cafe] Cabal and DB packages

[inormann]

This is how I successfully installed haskelldb-0.10 package with ghc-6.8.2
today:

Assuming you have downloaded and unpacked haskelldb-0.10 from
http://hackage.haskell.org/packages/archive/haskelldb/0.10/haskelldb-0.10.tar.gz

you need to append in haskelldb-0.10/haskelldb.cabal

  pretty, old-time, directory, old-locale

in line

  build-depends: haskell98, base, mtl 

and

  -fglasgow-exts

in line

  ghc-options: -O2

with that it should work:

    runghc Setup.hs configure
    runghc Setup.hs build
    runghc Setup.hs install
