Re: how to cabal-install with ghc-8.rc3 ?

Hi.

I would love to test rc3. Building (with 7.10.3) from source went fine. But then I cannot cabal-install anything:

random-1.1: installed package info from too old version of Cabal (key field does not match id field) Failed to install random-1.1

What is the recommended upgrade path?
