  • Seems to be an open issue at the moment on github: https://github.com/knu/ruby-unf/issues/11 – karlingen Apr 13 '15 at 09:56

  • Thanks a lot ! Same as the link. I've fixed this issue by simply reinstalling the Command-Line-Tools commandlinetoolsosx10.10forxcode6.2.dmg for Xcode 6.2 for OS X 10.10 from Apples Developer Download Page. – March Hare Apr 13 '15 at 10:08

It's a bug in the new xcode tools. It broke eventmachine in my case. See Missing C++ header <__debug> after updating OSX Command Line Tools 6.3 for answers with dummy files and reinstallation links. I downgraded to 6.2 and the problem went away.
