None, we have cabal-helper now. Woo :)

Known issues related to Stack

readPackageDb: inappropriate type

ghc-mod: $HOME/.stack/snapshots/x86_64-linux/lts-2.22/7.8.4/pkgdb/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (not a ghc-pkg db file, wrong file magic number)

Your Stack resolver uses a different GHC version from what ghc-mod was linked with, in this case:

$ ghc-mod --version
ghc-mod version 5.3.0.0 compiled by GHC 7.10.2

VS.

$ stack ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 7.8.4
