Hmmm... that doesn't seem quite right.
Here is what it should look like. These are screenshots from a windows installation, but it should be similar for a Mac or Linux install.
When you download the main game it should like this inside of The Tyrant 0.9.1 folder.

Then when you look inside the game folder, it should look like this.

This is, as you can see, where you add the SAZMOD folder.
If you are not seeing this file structure then I suspect something went wrong with the original game's download or installation. You also do not need to run
unren on the game to install the mod, as was the case in some previous versions. You just need to move the whole 'SAZMOD' folder into the 'game' folder.
I hope this helps.
