Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

/bin/sh: line 10: cargo: command not found

]: [The makefile runs `cargo` and `tar`. But both binaries are missing.]

Issue: You do not have `cargo` and `tar` binaries installed in the build system when you build the SRC.RPM.
Resolution: You have several options:

1) You can put in the Makefile a line `dnf install cargo tar`

2) Or you can switch in Copr build system to Custom method when you can manually call `dnf install` and then `make srpm`.
