Oops maybe this output is from cargo.

According to https://semver.npmjs.com/ the ^ (hat) means: include 
everything greater than a particular version in the same major range. 
cargo should thus accept up to 0.0.999 in this case as valid but does not.

Should I relax the version requirement? To what?
