Major versions of the same library are available, referenced by different paths. It works if they don't reference any global resources outside of their own package. If they do reference any global resources (such as the using the standard flag package, paths on the filesystem, mutexes etc.), then things can fail badly. Yes, this means if one of your dependencies pulls in a different major version of a package than used by other dependencies, then they can end up duelling over resources.
