Installing the sassc Ruby gem on a Mac. A debugging story

I wrote a blog post about a hyper specific issue that's already solved in the comments because that's what we used to do. Debug things, write blog posts about them and share. Whether it helps or not, it felt good to write and it feels good to share.
Learn a bit about how native extensions work and how to fix "Error 1" when installing the sassc gem on your mac. I hope you enjoy reading it half as much as I enjoyed writing it.

Ahoy, rubyists! I'm trying a new thing, which is to periodically publish a summary of the open-source work that I'm doing. Here's the first installment!

Shout out to my employer, 37signals, and to the handful of generous folks and companies who are sponsoring me on various platforms. 
Can anybody explain this? 
"hello, world.".scan(/\G(?:\w+|)/)
=> ["hello", "", "", "world", "", ""]
This is going to be a niche one, but...anyone using #ruby and the parslet gem to write a grammar?
I'm trying to capture everything up until a codeblock that starts on a newline. (Including a codeblock that has a prefix such as being indented). But I hit a speedbump.
Example of what I'm trying to do with runnable reproduction https://github.com/kschiess/parslet/issues/229.

We are down to 2 apps still using `heroku-20` stack.
Those app are actually ready to be upgraded since are not using #ruby 2.7 - which is the only reason why we were in the old stack in the first place.
Let's say we are done with this migration, the banner will be gone in the next deployment next week - yes, we do weekly releases.
feb 11, 2025. We are down to 8 apps still using `heroku-20` stack. All of them are #ruby web apps that are kind of important to schedule exactly when they can be upgraded.

ヒミツのgemを利用するアプリをHerokuにデプロイする2025年版

feb 06, 2025. We are down to 13 apps still using `heroku-20` stack.
The most difficult part so far are the problem with Sidekiq::Extensions::Delay** because we have very mucho `.delay` sprinkled here and there on our #ruby apps - yes, we still are in some Sidekiq 6.x
So, it's Feb 2025 and #Heroku apps using their heroku-20 stack starts to fail on builds, expected but I still don't like it.
We have only 17 apps, and very close to update them all to #ruby 3.x - the main reason why we are still in that stack. More info in the ALT text of the image below.
I think I'll share my progress here, and also if you have questions or something please do; been there, done that, bough the book, DVD, Blu Ray and 4K edition - and watched the musical at Broadway.
