The DRY principle issues usually apply very well to OO programming and the whole "framework" concepts, where individual libraries or pieces of the code cannot easily be reused for different projects. Another big issue in the framework case is the inversion of control, which further restricts how the reuse can happen and makes it very hard to reuse the code differently in an efficient way.
