as jeffz said if you want the latest the mightiest wine you should upgrade your OS (ubuntu 7.10) to the latester version which is 8.04 (and by 10/30 8.10) just connect at the internet and let it do its job - it will detect any new updates and inform you if you want them installed. you can find more info on how you do what at Google (http://www.google.gr/search?q=upgrade+from+7.10+to+8.04) after you've upgraded to 8.04 follow the link jeffz wrote, and you'd have the latest wine (also note that latest != best because something is fixed while something else gets broken)
