Installing dependencies fails with very same error, unfortunately.

I did the following to work around this:

I cloned this branch on GitHub: https://github.com/haskell/cabal/tree/1.22

Then, in the cabal-install folder I built the 'cabal-install' binary *without* using the existing version of cabal-install, then used the newly built 'cabal-install' to actually install the new 'cabal-install':

cd <folder which has cabal-install>

ghc Setup.hs

./Setup.hs configure

./Seup.hs build

dist/build/cabal/cabal install

You may need to install some dependencies first - using the old cabal-install worked fine for me for this, but maybe it secretly corrupted something behind the scenes. I haven't had trouble so far.

Hi!

I just did `sudo make install` on ghc 7.10.1-rc1, removed ~/.ghc and did `cabal update`. I'm now trying to upgrade to latest cabal by issuing `cabal install cabal-install`. I get the following:

```
...
on the commandline: Warning:
    -package-name is deprecated: Use -this-package-key instead
ghc: 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.

Does anyone know a quick-fix?

Thanks!
