Be able to cabal install haskell-platform

[anonymous]

Once this works:

$ cabal install
Resolving dependencies...
Configuring haskell-platform-2009.0.0...
cabal: Unknown build tool cabal-install
cabal: Error: some packages failed to install:
haskell-platform-2009.0.0 failed during the configure step. The exception was:
exit: ExitFailure 1

That is, cabal is able to track and install build-tools of unknown origin, we can put the haskell-platform.cabal file on Hackage, and it should be cabal-installable.

Duncan reports this is at least 6 months off.

Note that the immediate problem is fixed, we say what the "cabal-install" tool is in the Setup.hs file. This lets you install the platform meta-package using cabal if you already have cabal, alex and happy installed.

However the main problem remains, that cabal does not follow build-tools as dependencies. It currently only tracks build-depends, ie deps on libraries.

Changed to blue sky, since this depends on features in cabal-install which aren't implemented yet.
