Rust Nightly Error: Found value used as a type

When compiling with rust nightly (1.8) I get the following errors:

Well, you should use current "master". It changed API a little so it's not future-proof to use the old one anyway. I hope to release 0.5 in a week or two.

The rotor 0.5.1 is just released and travis shows that it's okay in nightly (0.5.0 was also okay, AFAIR)
