[DRE-maint] Bug#996514: ruby-terrapin: FTBFS with ruby3.0: ERROR: Test "ruby3.0" failed: Failure/Error: undef_method :exitstatus

[Antonio Terceiro]

Source: ruby-terrapin
Version: 0.6.0-2
Severity: serious
Justification: FTBFS
Tags: bookworm sid ftbfs
User: debian-ruby at lists.debian.org
Usertags: ruby3.0

Hi,

We are about to enable building against ruby3.0 on unstable. During a test
rebuild, ruby-terrapin was found to fail to build in that situation.

To reproduce this locally, you need to install ruby-all-dev from experimental
on an unstable system or build chroot.

Relevant part (hopefully):

> Using `should` from rspec-expectations' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` with `config.expect_with(:rspec) { |c| c.syntax = :should }` instead. Called from /<<PKGBUILDDIR>>/spec/terrapin/command_line/runners/backticks_runner_spec.rb:19:in `block (2 levels) in <top (required)>'.
