design pattern question

A library is a tool to speed up your development and it should be build to add to every organizational pattern. So a library is not a part of the MVC pattern but you can build it to take advantage of an organizational pattern.

The problem with some libraries is that they are too tightly coupled with an organizational pattern because they are build when using a particular pattern. As for the ACL/user admin library IMO it's more a module than a library because you have models, views and controllers and then there are methods of the module that are used in other controllers and views.
