OSX & linux pacman binaries for devkitPro provided libraries.
Do not attempt to install the files from the .deb manually on non Debian systems, see https://devkitpro.org/wiki/devkitPro_pacman for instructions. Arch, Fedora and Gentoo based distros are covered explicitly there.
On macOS you should be able to just run the .pkg
For debian based systems
sudo dpkg -i devkitpro-pacman.deb
This command will also work on WSL but a symlink may need to be created first
sudo ln -s /proc/self/mounts /etc/mtab
