 * Just follow the install instructions letter by letter. After that, apologize 
   to the team and upgrade your rating to, at least, 3 stars.
 * I have to admit though that the** install process is highly unusual and error-
   prone**, but that does not mean you can skip reading the docs and then belch 
   out a one star review.
