With ghc 7.4.1, cabal-install 0.13.3 and Cabal 1.14.0, % cabal install --avoid-reinstalls sbv-2.2 fails to find a plan without reinstalls, and recommends --solver=modular. % cabal install --solver=modular --avoid-reinstalls sbv-2.2 reinstalls template-haskell-2.6.0.0, which breaks the GHC installation. I've added the suggested --constraint='template-haskell==2.7.0.0' option as a workaround, but it seems the --avoid-reinstalls option is being ignored.
