For historical reasons, the 'inputs' in the phase contains both the native-inputs and native- inputs in the phase is #false when compiling natively, which can be confusing (maybe that can be addressed someday). I suggest: (lambda* (#:key native-inputs inputs #:allow-other-keys) (substitute* "Makefile" (("./fennel") (search-input-file (or native-inputs inputs) "/bin/fennel")))))
