I'll take a shot. If I understand it correctly, basically components have dependencies. For example, A depends on B and B depends on C, etc. If you have A depends on B... and somehow along the path you have a cycle, eg. E depends on A, you have a problem because in order to install A, you need to install B, C,... E. But in order to install E you need to install A first. So you have to break the dependency cycle.
