Actually, there is most likely a spring-loaded tensioner pulley that is stuck. There was one that you had to release with a ratchet or wrench. Check that it moved back all the way. Just because it moved back a little on its own doesn't mean it went far enough. The clue is the belt will appear to be only about an inch too long.
If you find the belt is two or three inches too long, it is almost certainly routed incorrectly. I've been confused a few times after following the diagram on the side of the engine. Often they will show the routing with and without an AC compressor. When there's no compressor, on some engines there's an idler pulley instead, but on others, the routing is considerably different because other components like the power steering pump can be located in a different place.
