Well, after getting pissed at this project because it was the only link between me and Lua-powered gossip npcs, I finally decided to look into the whole deal. Took all of a few minutes sadly and I wasted way more time than that getting mad at some of the devs here for almost no reason. Personal stuff aside, here's what I found.

Apparently, the gossip functions in the svn vary from the ones used in almost any example script I could find. I guess the easy way to convey this is throw together a function reference and give you an example script.

GossipCreateMenu
Called from - Unit
Arg1 Integer - Text ID. Not entirely sure what it's used for but I'm guessing high and random numbers are a safe bet.
Arg2 Pointer - Player you're creating the menu for.
Example: Unit:GossipCreateMenu(3543, Player)

GossipMenuAddItem
Called from - Unit
Arg1 Pointer - Player you're creating the menu for.
Arg2 Integer - Icon display ID for gears,chat bubbles, and whatever else there is
Arg3 String - Displayed text for this menu item
Arg4 Integer - Number used with Gossip_Select
Arg5 Integer - Code menu. Shown(1) or not(0)
Example: Unit:GossipMenuAddItem(Player, 4, "Text displayed to the player!", 0, 0)

GossipSendMenu
Called from - Unit
Arg1 Pointer - Player to send the menu to.
Example: Unit:GossipSendMenu(Player)

Note: I'm not taking credit for this script in full but I simply made modifications to it to get it to work. I don't remember who the original creator is.
