Создание стека Ruby на Windows Server: msvcrt-ruby18.dll

Я пытаюсь запустить mongrel_rails, но получаю следующее:

    the program can't start because msvcrt-ruby18.dll is missing from your computer

Затем Руби дает мне следующее:

    C:\Users\Administrator>mongrel_rails
    C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 126: The s
    pecified module could not be found.   - C:/Ruby193/lib/ruby/gems/1.9.1/gems/mong
    rel-1.1.5-x86-mingw32/lib/http11.so (LoadError)
            from C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require

            from C:/Ruby193/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5-x86-mingw32/lib/m
    ongrel.rb:12:in `<top (required)>'
            from C:/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require

            from C:/Ruby193/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5-x86-mingw32/bin/m
    ongrel_rails:11:in `<top (required)>'
            from C:/Ruby193/bin/mongrel_rails:19:in `load'
            from C:/Ruby193/bin/mongrel_rails:19:in `<main>'

Я пытался удалить json и переустановить с --version=ruby безрезультатно. Я также пытался использовать mongrel --pre, что приводит к другому набору ошибок:

    NOTE: Gem::SourceIndex#each is deprecated with no replacement. It will be remove
    d on or after 2011-11-01.
    Gem::SourceIndex#each called from C:/Ruby193/lib/ruby/gems/1.9.1/gems/gem_plugin
    -0.2.3/lib/gem_plugin.rb:112.
    !!! Path to log file not valid: log/mongrel.log
    mongrel::start reported an error. Use mongrel_rails mongrel::start -h to get hel
    p.
