Hi, Antonio.  Thanks for the quick response!

The ruby-fast-xs version in play at the time (now superseded by a +b3
build against ruby 2.3) had, per
https://buildd.debian.org/status/fetch.php?pkg=ruby-fast-xs&arch=m68k&ver=0.8.0-3%2Bb2&stamp=1456486333&raw=0,

Depends: libc6 (>= 2.1.3), libgmp10, libruby2.2 (>= 2.2.0~1), ruby (>= 1:2.2)

However, there was (and still is) no upper bound on the ruby
metapackage's version, allowing for mismatches.
