Ruby on Rails installation hangs while building nokogiri gem

Hello,

I’m trying to install Rails on a fresh copy of iSH with Ruby set up and running exactly as described [in the Wiki](https://github.com/ish-app/ish/wiki/Running-Ruby-Programs).

Now, in an attempt to install Rails, I’ve run `gem install rails`, which goes on to install a number of dependencies, until it hangs at `Building native extensions` while installing `nokogiri` gem.

I left my iPad screen on for 7+ hours with the iSH app in the foreground; however, there is no progress from that point on. It appears to have hung (I can’t terminate the process with control + C).

This is on iSH 1.2.3 (Build 298), iPadOS 15.4.1, and iPad Pro 2018. My `ruby -v` reports `ruby 2.7.6p219 (2022-04-12 revision c9c2245c0a) [i586-linux-musl]`.

Here’s the full log (with `--verbose`):
```
Welcome to Alpine!

Start with the Wiki's “Running Ruby Programs” page and reproduce `gem install rails --verbose` on iSH 1.2.3, focusing on the reported pause while building `nokogiri-1.13.4`. The issue is done when the native-extension installation either completes reliably or the supported limitation and required setup are documented.
