rubygems 1.3.6 安装失败

Question

我已经从源代码安装了 ruby​​ 1.9.3 并下载了 ruby​​gems 1.3.6 也是源代码。查看手册，我解压了压缩包并输入 ruby setup.rb这是我得到的输出:

/usr/local/lib/ruby/1.9.1/rubygems.rb:206:in `try_activate': undefined method 
`find_by_path' for Gem::Specification:Class (NoMethodError)
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:59:in `rescue in require'
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:35:in `require'
        from /root/rubygems-1.3.6/lib/rubygems/config_file.rb:50:in `<class:ConfigFile>'
        from /root/rubygems-1.3.6/lib/rubygems/config_file.rb:28:in `<top (required)>'
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from /root/rubygems-1.3.6/lib/rubygems/gem_runner.rb:8:in `<top (required)>'
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from setup.rb:25:in `<main>'

这是在 CentOS 5 上完成的

Rubygems 的当前稳定版本是 1.8.24，您安装 1.3.6 的具体原因是什么？
