I managed to build all of our Haskell packages (except for some usual suspects that fail for other reasons). It’s not so bad, but it’s a bit of a hack. I’m now wondering why Guix’s treatment of “LIBRARY_PATH” is not just solving this outright without the need for those flags. Before I consider pushing the patch, I’m going to answer that question. Ideally, Guix could do more of what it’s good at: understanding the complete package graph. :) -- Tim
