Devise & OmniAuth facebook connect

Hi,Im new to this forum.
Im having a problem on a simple facebook connect.
I tried to follow all the tutorial on the website but its not work for
me.
gem using : devise ,omniAuth
rails version : 3.0.7
I want to ask what rails version ,devise version, omniAuth version is
gud to use to apply in my application? It come to my mind because i
tried out some of the tutorial, they need omniAuth of lower version like
0.1.x or 0.2.x .
I would like to seek some help/advice that what is the gud gem for me to
use to connect facebook. I chose to use omniAuth cz it can apply on
multiple account such as google ,facebook and etc. Is that im on the
correct path?
currently im refering tutorial :

https://github.com/plataformatec/devise … A-Overview
https://github.com/plataformatec/devise … :-Overview
http://railscasts.com/episodes/235-omniauth-part-1

i have to add on that, when i connect ,mostly it will generate an error
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B:
certificate verify failed
i tried to solve by referring online solution,but for window,i do
exactly the same,but it still the same
