Hui,
I got it working simply by creating a bin directory in my home directory. ie: /home/<user>/bin
Then run the installer and it works ok. This is the basic game and the base program will prompt to download the latest version, which is a nice touch. (Hate having to look for versions of programs).
You can add and modify the basic skins (HUD layout, coloring, etc by creating a skin folder under the .vendetta dir (once you've installed it!) Then look at the wiki site (http://www.vo-wiki.com/wiki/Main_Page) and download the zip to that skins directory (most zips will actually contain a folder called skin, so you copy it in. Modify the config.ini and add skin=skin/ under the vendetta section and your away.
I'm now using the insurrection skin, so thought I'd share how I did it, for other Ubuntu users!
