Comment (by kencu):

 Then -- just use the fallback librsvg all the time, except on 10.14 that
 can't build anything universal?

 Or just totally forget this rust nonsense, and just use the fallback
 librsvg all the time, everywhere. They were a bit adventuresome to default
 on a rust-requiring version anyway, if you ask me.
