That's strange. It's working fine for me on Mavericks. The ruby.h header can't find <string.h>, which is stdlib. Could it be a problem with Xcode / xcode-select? I'm not an expert, but maybe you could try this?

echo "#include <string.h>" > /tmp/gub.c && clang /tmp/gub.c

Thanks for you help. You were right, it was an issue with xcode. I've upgraded to Xcode 5.0.1 and installed latest developer tools with xcode-select. After accepting the license using 'xcode -license' I was able to install your gem.

Before upgrading to Mavericks it was working fine, hence I assumed it might be some kind of compatibility problem. Sorry for wasting your time.

Glad to hear it, thanks for following up!
