hmm, not sure why baca would need so many requirements. I installed baca using pip as per (https://github.com/wustho/baca), on a hedless ubuntu based server. Maybe on Arch it would need to install / update python packages?
You could also try epy (https://github.com/wustho/epy) which is also a terminal based epub reader.
