This is actually not a bug, but simply means a dependency cycle has been detected in the dependency chain, and that pacaur is unable to further proceed without manual intervention and bails out.

This is either due to an error in the PKGBUILDs, or in some case one of the dependency requires to be bootstrapped so it can be compiled without its real dependency. Please check with the maintainer.
