Can't build charlock_holmes native gem - ruby-on-rails

Question

Trying to install and build native gem charlock_holmes version 0.7,3 with bundle install and getting an error. I believe I have all the dependencies but cannot figure out the error messages. Any help is appreciated.
I'm using Archlinux, ruby 3.0.0p0 and rubygems 3.2.3.
Stackoverflow is forcing me to add more stuff since it says "your post is mostly code", but there isn't much more to say about it... ¯_(ツ)_/¯
