I think that should be documented.

I did get it built, but the various error messages in particular were
rather un-obvious.  For instance, does this imply some missing/bad
specification and, if so, where?

  Registering vector-0.10.9.1...
  cabal: Error: some packages failed to install:
  darcs-2.9.8 depends on haskeline-0.7.1.2 which failed to install.
  haskeline-0.7.1.2 failed during the configure step. The exception was:
  user error (The package requires Cabal library version -any && >=1.16 but no
  suitable version is installed.)

I guessed at "cabal install cabal-install", which eventually got me
going.
