@atyh Building from source is fine and xbps-src makes it even easier. But some hardware is just old. Building Firefox (yes, sometimes you need it) on my PowerMac G5 takes about two full days 😮
I don't usually patch it and I'm fine with default optimizations, so I'd just go with binary. Unfortunately Daniel no longer builds those for PPC-BE MUSL systems, so I build everything myself. Sometimes it's just a waste of computing power 🤷
