While I've not worked with it much, Nix seems like a complete,
well-thought system for building out multi-versioned package
installations. Have you looked at it? What do you think?
Finding myself in a similar situation, I wonder if it's not
ultimately better to leverage the work of the Nix team,
instead of building a "simpler" system for Haskell (and then
later for Ruby and then...).
