Arduino-ide-1.6.0 + due on the Raspberry Pi

I have a raspberry pi 2 running wheezy-based raspian linux. My Arduino IDE is v1.0.1 but I want to get up to 1.0.5 if I can in order to use a library that will not work on my UNO without the higher rev IDE. Is there a path to get there in wheezy? If not, is there a detailed howto on going from stable wheezy to jessie?

Thanks,
Joel
