Ruby言語 (ruby/ruby) のビルド時に、`make miniruby`がこけた

エラー詳細

以下どドキュメントに従い、ビルドしようとした。

ディレクトリ構成は以下。Rubyのコミットバージョンは、e1683b4

- workdir
   - ruby
      - build

workdir/ruby/build 配下で、以下を叩いた。

(短期的)解決方法

workdir/ruby/tool/lib/vcs.rbを以下のように書き換えた。

diff --git a/tool/lib/vcs.rb b/tool/lib/vcs.rb
index 8566d72349..0436c0665e 100644
