[Haskell-cafe] cabal Setup.hs configure - cabal doesnt produce a setup-config

Hi, I am trying to install nanocurses, but cabal isn't creating the setup-config file in dist/ I have run (and re-run) runghc Setup.hs configure The first time it complained about mpg123 (whatever that is) so i installed the other dependencies - unix & bytestring Then i tried to re-run setup configure for nano again. Configure creates the dist directory but no files. I have deleted and untarred the files and retried,but to no avail. Any clues? Thanks. (OS: Ubuntu hardy, GHC: 6.8.2)
