Are LDS not Christian because they have a different Bible?

Their Bible mentions the need for Apostles and Prophets, Christ being the chief corner stone. It also mentions Priesthood, Aaronic and Melchizedek, man will not be without woman in the kingdom of Heaven (eternal marriage), Temples, Christ will speak to his "other sheep"(new scripture) Israel will be gathered, (missionary work) and to top it off it says the Lord won't do anything in our day except he reveals His will to his Prophets, so He has restored the old fashioned way of doing things with Apostles and Prophets.I think theirs is called the King James version.
