Looking into Raku again and, while the language seems pretty neat, the bare-bones standard library really throws a wrench in the fun. Gentoo doesn't even package the 'zef' package manager, so I'd have to grab that from source manually. Even with that done, there's the typical wild west of uncoordinated package development: always a bunch of competing packages for the same functionality, many unmaintained, some in eternal beta (and not promising a stable API), some missing crucial functionality, and some depending on 20+ other packages. Choose your poison.
Meanwhile in Crystal land I've written several useful programs that had no dependencies besides the compiler and standard library, both of which are within reach of a single `emerge`.
