For those who want to try bleeding edge I've added 64bit package of EFL 1.20 and E22 to the testing branch. They install well enough, but were giving me fairly frequent segfaults while playing with things in my VM.
After adding the b4testing branch to your repos you can install E22 with the commands:
sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install e22
Note that this will replace your current Moksha install, so if you have a profile setup you like I'd recommend backing up your ~/.e folder before install E22.
