Have you checked whether the inputs are referenced in `guix gc -R /gnu/store/...item`? If not, we'll need to make it record the absolute paths of the dependencies somehow. Often this can be done with '--with-foo=(string-append (assoc-ref inputs "foo") "/bin/foo"' in the configure step. Another approach is to substitute those commands with the full path directly in the code. > So far they are in (inputs). Are those supposed to be installed by the users > themselves? For optional dependencies (i.e. if mps-youtube gracefully handles missing ffmpeg), leaving it up to the user is good (but then it should not be an input). For "hard" runtime dependencies, the absolute paths must be recorded so that they won't get garbage collected.
