[Chris West (Faux)]

Source: ruby-org
Version: 0.9.1-2
Severity: serious
Tags: sid stretch
Justification: fails to build from source
User: reproducible-builds at lists.alioth.debian.org
Usertags: ftbfs

Dear Maintainer,

The package fails to build:

  2) Orgmode::Headline should understand a single tag
     Failure/Error: h.should have(1).tags
     NoMethodError:
       undefined method `have' for #<RSpec::ExampleGroups::OrgmodeHeadline:0x000000022b5398>
     # ./spec/headline_spec.rb:49:in `block (2 levels) in <top (required)>'

  3) Orgmode::Line should tell comments
     Failure/Error: line.comment?.should be_true
       expected 0 to respond to `true?` or perhaps you meant `be true` or `be_truthy`
     # ./spec/line_spec.rb:9:in `block (3 levels) in <top (required)>'
     # ./spec/line_spec.rb:7:in `each'
     # ./spec/line_spec.rb:7:in `block (2 levels) in <top (required)>'

....
