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.
Failed to install zlib-0.5.4.2
cabal: Error: some packages failed to install:

mtl-2.2.1 failed during the building phase. The exception was:

text-1.2.0.3 failed during the building phase. The exception was:

zlib-0.5.4.2 failed during the building phase. The exception was:

```

Does anyone know a quick-fix?

Thanks!
