[Pkg-haskell-maintainers] Bug#778987: mismatched versions of cabal-install and Cabal result in build failures

[Joey Hess]

Package: cabal-install
Version: 1.20.0.3-1
Severity: normal

Since Cabal is back at version 1.16.0, a package with a custom Setup.hs
will be built linked against that. However, cabal-install 1.20 puts
things in the default ~/.cabal/config that cause such a Setup to crash.

For example:

joey at darkstar:~/src/git-annex>cabal configure
Config file path source is default config file.
Config file /home/joey/.cabal/config not found.
Writing default configuration to /home/joey/.cabal/config
Warning: The package list for 'hackage.haskell.org' does not exist. Run
'cabal
update' to download it.
