Is there a quick guide to install this ?

I have just switched from windows to Ubuntu, Help!

I got 0.9.0 installed via PPA but the PPA is not updated yet ( + I would like to know how to do it without)

I have :-

Downloaded bitcoin-0.9.1-linux.tar.gz

Then tar xvzf bitcoin-0.9.1-linux.tar.gz


This gives me a folder with bin + src but no ./configure. src has but that  fails.

Obviously I just don't get it
