Examples don't build

Looks like there is a problem with tokio. The same failures occur for greeter_client:

Works fine on my notebook:

Which version are you using? 0.3.0 should work, 0.2.* shouldn't.

I tried it on another system and it worked fine too. Not sure what my problem is on this one. Sorry.

Fixed it on this system with a cargo update. After doing that it built just fine.
