Your code imports (guix utils), but (guix utils) is not present within the module closure present at build time. Did you mean (guix build utils)?

I know little about jpm, but in my opinion you ought to let the user customize the flags passed on to jpm at least in the build target -- not so sure about check and install. If janet-build-system allows some degree of customization, consider also letting the user override the test-target. Regards, Leo
