I’d be very happy to contribute to this effort. In fact, I’ve already spent some of time addressing these issues. Halcyon already provides a method for installing GHC, cabal-install, build-tools, and other Haskell programs — on OS X, and many Linux distributions. FreeBSD and Windows are on the roadmap. Additionally, Halcyon allows you to declare native OS libraries as build-time (or run-time…) dependencies for Haskell programs. They will be installed into a user-controlled directory, by wrapping around the native OS package manager. Currently, this is supported on Debian-based and RedHat-based Linux distributions, which partially implements a long-standing cabal-install feature request: https://github.com/mietek/halcyon/issues/38 https://github.com/haskell/cabal/issues/571 See the Haskell Language source code for an example: https://halcyon.sh/examples/#haskell-language See the Halcyon reference for details: https://halcyon.sh/reference/#halcyon_sandbox_extra_os_packages https://halcyon.sh/reference/#halcyon_extra_os_packages -- Miëtek https://mietek.io
