what do I have to do, is there a problem with dependencies? How do I fix those? I am on catalina.
I repeatedly get this error and have already looked for the directory.. doesn't exist.

Older macOS versions might work, but we don’t officially support them. To install Jekyll on macOS, you need a proper Ruby development environment. While macOS comes preinstalled with Ruby, we don’t recommend using that version to install Jekyll. This external article goes over the various reasons why you shouldn’t use the system Ruby.
If this is a feature request, please consider building it first as a plugin. Jekyll 3 introduced hooks which provide convenient access points throughout the Jekyll build pipeline whereby most needs can be fulfilled.

Sam's comments are correct. XCode's ruby framework is broken. A workaround is to make a symbolic link:
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0
ln -sf universal-darwin20 universal-darwin19
With this, I was able to successfully build all the native extensions.
Note: You should change your path segment MacOSX11.1.sdk according to your local Xcode SDK installation.
