I recently wrote about working with multiple Ruby versions on OpenBSD which still works just fine, but I noticed a bug when trying to build a couple of my Jekyll projects locally:

NotImplementedError: dart-sass for x86_64-openbsd7.5

For reference, these projects are being built with Ruby 3.3.0 against Jekyll 4.3.3. After doing some research, I came across this ticket that was somewhat buried in the search results: https://github.com/jekyll/jekyll/issues/9493

The issue seems to be caused by the lack of the dart-sass gem in OpenBSD. Luckily there is a fairly easy fix - we just need to hard-set the jekyll-sass-converter version in our Gemfile:

gem 'jekyll-sass-converter', '~> 2.2'

After making this change and running bundle install again, my Jekyll projects started building (and serving) perfectly! Hopefully this helps others trying to build their own Jekyll projects on OpenBSD.
