The executable are searched on > $PATH. Option #2 is a bad idea (propagated inputs should be used only as a last resort.) Adding the tools as inputs is only useful if there are tests that actually run dtrx; otherwise it’s useless. Then you have two options: 1. Let dtrx search for tools in $PATH. The downside is that it won’t work out-of-the-box, as in “guix environment -C --ad-hoc dtrx”. 2. Hard-code the absolute file names for the tools in question in dtrx. That way ‘guix pack dtrx’ will be self-contained, etc. I’d prefer #2. Ludo’.
