For building tools requiring a compiler, the current expectation across Guix packages is that the user provides the one it wants. Even if using GCC, you may want to use a different version, and rebuilding GHC just to do so is... expensive. I'm closing, but if you'd like this to be further discussed you could start a thread on guix-devel. -- Thanks, Maxim
