Install latest version of radicale

Hello!
I have installed package radicale-1.1.1-r2 (http://pkgs.alpinelinux.org/package/edge/testing/x86_64/radicale).
However, I would prefer to run latest version that's e.g. available with archlinux (https://aur.archlinux.org/packages/radicale/).

This newer version depends on

python-setuptools python-vobject
python>=3.3
python-setuptools (make)
python-passlib (optional) – bcrypt support for htpasswd access

Question:
What do you propose to install latest version of radicale?
