Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

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/extendmatrix_spec.rb:16:in `block (2 levels) in <top (required)>'.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
