When I say

I get this
ghc-stage2: ghc no longer supports single-file style package databases (dist/package.conf.inplace) use 'ghc-pkg init' to create the database with the correct format.
Now, this is an old build tree, and I could blow it away entirely, but maybe there is something else going on. What should I do?
What does `cabal --version` say? If it doesn't say something like $ cabal --version cabal-install version 1.21.1.0 using version 1.21.1.0 of the Cabal library you probably need a newer one (in which case you should build the `cabal` binary from Git, and to make life easier compile `Cabal` and `cabal-install` with GHC 7.8.x rather than GHC HEAD) Cheers, hvr
