[Haskell-cafe] ghc 7.10.1-rc1 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.

[Doug Burke]

I ended up installing both Cabal and cabal-install (from GitHub) using ghc
7.8.4. After that things seemed to get better with ghc 7.10 RC1 (which was
using my newly created cabal-install command-line tool with the Cabal libs
from ghc 7.10). Or at least, I think that's how I got it working.

HTH,
Doug
