Hi, I currrently try to package a go package that fetches the version from Buildinfo like this

func GetVersion() (ret string) {
	if b, ok := debug.ReadBuildInfo(); ok && len(b.Main.Version) > 0 {
		ret = b.Main.Version
	} else {
		ret = "unknown"
	}
	return
}

Building that with nix gets (devel) as version, how can I set the version to the real package version?
