Indeed

Try building cabal-install using revision e7e7ce1029707a67d26e6dc29de11141734898e3

I don't doubt that it builds with the Cabal in cabal-1.16 branch but that does not help Haskell Platform 2012.4 unless there will be a ghc-7.6.2 release before it. I think it is better to think of Cabal-1.16.0 as the Cabal in ghc-7.6.1... Jens

Hi,

I managed to build cabal-install-0.25.2 (from the cabal-1.16 branch) with ghc-7.6.1 Cabal.

However the use of viewAsFieldDescr in cabal-install/Distribution/Client/Config.hs causes problems due to the:

error "Command.optionToFieldDescr: feature not implemented"

Can it be so that ghc-7.6.1 ships with an older snapshot of Cabal-1.16? Try building cabal-install using revision e7e7ce1029707a67d26e6dc29de11141734898e3

If that's the case then that's really bad. GHC should not ship with random snapshot of branches.
