My first question will always be: Is it Arch, or a derivative?
$ lsb_release -a
Which AUR helper did you use to install eddie-ui, if any?
All the things posted really point at eddie-ui not being properly installed. Not sure how that can happen with makepkg being used. Try it manually.
$ git clone -q https://aur.archlinux.org/eddie-ui.git
$ cd eddie-ui
$ makepkg -fsicC --noconfirm
