 Replying to [comment:1 duncan]:
 > The problem is that cgi-3001.1.7.1 uses syntax that is new in Cabal-1.6
 and your version of cabal-install is using Cabal-1.4. So it's not that the
 file is missing (it isn't) but the .cabal file cannot be parsed.

 Thanks, but upgrading Cabal lib and cabal-install haven't helped. I
 couldn't upgrade Cabal with cabal-install ("No packages to install") so I
 downloaded Cabal 1.6 and installed it myself then used ghc-pkg to
 unregister older version of Cabal. Then I reinstalled cabal-install but it
 is still reporting the older version of cabal:

 ##############

 And cabal upgrade still doesn't work. I thought I might need to clean and
 reconfigure the cabal-install package myself so I tried that too, manually
 deleting ~/.cabal/bin/cabal and using `runhaskell Setup.hs --user ...' etc
 in the packages directory. After that I am still told I'm using Cabal 1.4.

 Thanks,
