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:
