guix: Can't run natively on MacOS

Unfortunately the GNU immutable package manager, Guix, can not be installed on MacOS. It sounds like it's quite dependent on GNU's libc and so won't run on the Darwin based MacOS.

This is a shame because Guix uses a standard general purpose programming language, GNU Guile Scheme, for its DSL rather than the highly specific custom DSL that nix (the package manager) uses, nix (the language).
