Having just checked myself I don't find anything called Dvergr Gates either.
I can only assume they are referring to the Hexagonal Door which is a current late/end game structure piece which will not be available until you reach Mistlands.
By then you have more or less completed the game making the need for the gates pretty much obsolete.

What we need is something that can be built in early to mid game, and that is where your suggestion comes in.
