Great! If you have time and interest please revise our compilation instructions for macOS (section 4.7 in the Contributor's Guide), which are severely out of date... Ideally, the recipes for building the development version on both Homebrew and MacPorts should be updated, too. At least the one from MacPorts still uses guile2.x, which is no longer supported in the 2.25 series. Werner
