gem本体のインストールは成功している。

$ gem install tdiary

Parsing documentation for tdiary-3.2.2.20130507
Before reporting this, could you check that the file you're documenting
has proper syntax:

  /Users/machu/.rbenv/versions/2.0.0-p0/bin/ruby -c ChangeLog

RDoc is not a full Ruby parser and will fail when fed invalid ruby programs.

The internal error was:

        (NoMethodError) undefined method `<' for nil:NilClass

ERROR:  While executing gem ... (NoMethodError)

ruby 2.0.0でrdocがChangeLogの解析に失敗しているのが原因。ruby 1.9.3ではエラーは発生せず。

類似事例あり。rdoc側に報告したほうがいいのだろうか。

rdoc が core 同梱のものかどうかで別れますね...

rbenv環境ですが、rdocの実体はgemですね。

$ rbenv which rdoc
/Users/machu/.rbenv/versions/2.0.0-p0/bin/rdoc
$ ~/.rbenv/versions/2.0.0-p0/lib/ruby/gems/2.0.0/gems/rdoc-4.0.0/bin/rdoc --version
rdoc 4.0.0
