When I try to run the HelloWorld example as run Rack::HelloWorld using rackup config.ru, I get the following error:

The error is repeated several times.

Am I doing something wrong?

I am on Mac OS X and use david 0.4.0.

I could only try it in a OS X 10.9.5 VM (RUBY_PLATFORM also is x86_64-darwin13.0). Which version do you use? Originally, I tested on MRI versions 2.1.4 and newer. Now I installed 2.1.1 in my VM and everything works for me.

However, I changed the way socket options are set with setsockopt (from symbols to constants) and assume this should work now. I already closed the issue, feel free to reopen if it still does not work with the current master.

Thanks for reporting!
