It's not uncommon to have to build things because you've updated earlier than some others. I remember waiting hours for Rust, webkitgtk, or cataclysm-dda to build on multiple occasions. Sometimes just waiting another day would mean a substitute was available. You could also update your current profile with the exclusion of a few packages, such as the ones that have no substitutes. This is nice, but because it updates your current profile, then you can't remove something you were planning to remove via your package declarations, you're introducing your state then. A temporary issue that gets fixed when you can next apply your package manifest, though.
