error while running install.sql in community auth

Remember, this is the same exact error from the first install if you look at the start of this post. If I botched it twice the same exact way, that would be a huge coincidence. Have you tested changing $config[user_table] to another table name? I guess I can go back and change my own code to use another name (in dozens of places) for 'users'. Has anyone else had this error?
