You will need to add perl and python to the native-inputs field of your rust-rustscan-2 package for it to see those two programs. When packages are built, the building happens in an isolated environment distinct from your shell environment, so packages you install through "guix package -i" or "guix install" won't be seen in the package's build environment. https://guix.gnu.org/en/manual/devel/en/html_node/package-Reference.html#package-Reference describes the various fields including three different types of inputs, but my rule of thumb is that if the package depends on and is linking to a library then the library package is an input, and if the dependency is a program that needs to be run as part of the build (such as the rustscan package trying to run perl and python3) it should be a native-input. HTH!

Cheers,
Kaelyn

P.S. I've not packaged any rust code, but from what I recall rust packages that use cargo-build-system are a bit anomalous in that they have to declare the rust packages they depend on in a #:cargo-inputs argument instead of the normal inputs package field.
