I´m a bit at a loss regarding buildings.
e.g. in my current game I have two elven cities. In one I have built a harbor. When I go to the 2nd the harbor building is checked as "already existing elsewhere" however I can´t build a shipyard building (that requires a harbor). Or in a monsters city I want to build the tax officies which needs the rat guild - in the other monsters city I can´t build the tax office despite the building list stating that I already own a rat guild in another city...

Does that mean that I always have to build all buildings in one city if I want to build the next building that depends on it?
Or do I miss something like that the cities controlled lands have to be connected to have the buildings interact with those of the other cities?

Each city's build tree is independent of other cities. To build a shipyard in a given city, you have to have a harbor in that city first. The checkboxes are useful to know that somewhere you already have that building, so if you're only building it to gain it's empire-wide effect (transporting units across water, in the case of a harbor), then you don't need to build it. This is helpful with perks and unit-production buildings.
