It appears that you might have to install from source. I'm at work though so downloading the package isn't an option for me. If you need instructions on how to install from source here is a good place to start: https://help.ubuntu.com/community/CompilingEasyHowTo
Just as fair warning, installing from source does have the possibility of breaking your system if done wrong or screwing other things up. I've done it plenty of times with little to no problems though.
