[Chris West (Faux)]

Source: ruby-jsonify
Version: 0.4.1-2
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:

/usr/bin/ruby2.1 /usr/bin/rspec --pattern ./spec/\*_spec.rb
...................F.............................F..

Failures:

  1) Jsonify::Builder attributes! should allow create object with attributes of another object
     Failure/Error: json.attributes!(object, :id, :name)
     NoMethodError:
       undefined method `id' for {:id=>1, :name=>"foo"}:Hash
     # ./lib/jsonify/builder.rb:65:in `block in attributes!'
     # ./lib/jsonify/builder.rb:64:in `each'
     # ./lib/jsonify/builder.rb:64:in `attributes!'
     # ./spec/builder_spec.rb:152:in `block (3 levels) in <top (required)>'

  2) Jsonify should be true
     Failure/Error: it('should be true') {true.should be_true}
       expected true to respond to `true?` or perhaps you meant `be true` or `be_truthy`
     # ./spec/jsonify_spec.rb:3:in `block (2 levels) in <top (required)>'
