I'd guess that you just put them in the folder with the game. gconf and gtk2 are both quite old so maybe check if there's an update for RPG Maker. And yeah, these two are the only ones missing
Aside from that, the content of this update was very good. I enjoyed it a lot, especially when Welkin gets to play with Rowley's nipples and ass. I hope Welkin gets to top Rowley, dominantly, and not just once
