> Is there a Ruby module with no C extension? Why is the "with no C extension" part important to you?

  This is important if you want to use JRuby.

    There's a protobuf java library.

      And a jruby messagepack library

    Exactly! Also IronRuby. Or MRI on Windows for a lot of extensions, which just won't build there.

  By the way, there is a pure ruby version, not sure why you'd use it over the cext though: https://github.com/hiroshinakao/msgpack-pure https://github.com/hiroshinakao/msgpack-pure

    JRuby. Windows, if you don't have the compile stuff installed. This could be alleviated with Ruby FFI on top of a really good C implementation, but FFI is tricky.
