Daniel, Steve, thanks for your input. I'll hold off uploading another
librmagick-ruby, as you say.

Tim Hunter (RMagick author) echoes your comment:

In this particular case, the ImageMagick folks changed a structure that is
shared between IM and C applications that link with IM. Probably they
shouldn't have but there's no stopping them. I have to test against every
release of IM to see if some API has changed since the last release. And
Christy will change the API on any release boundary. They had this under
control for a while but since 6.0.0 they've gone back to their old bad
habits.
