It depends on quickjs for the JavaScript implementation, which should be fairly simpler to compile on a hand rolled Linux. I'm not so sure about PCRE though
Oh I'm sure the actual work to compile those packages is not much. It's more to do with keeping the number of packages on my system to a minimum.
Actually I would not be surprised if the JavaScript engine can be omitted with just a little bit of patching work... assuming there's not actually a build configuration that leaves it out. I've found that with some software projects and their dependencies, "required" does not always mean required.
