I noticed that you mentioned yaourt. This tool is generally not recommended for use. It is insecure due to sourcing PKGBUILDs before the user has a chance to read them.
Consider using a different AUR helper. pacaur is generally considered a good alternative. It has very similar usage and syntax, allowing easy switching. Here is a link to its AUR page. In addition to being vastly more secure, it has a friendlier interface. It asks for package confirmations at the beginning of the installation process, allowing unattended installation.
cower - для поиска и проверки обновлений
git - непосредственно для скачивания и обновления из aur
makepkg - для сборки
repose - для управления локальным репо
В принципе repose и git из этого набора можно выкинуть и заменить их функциональность на cower и repo-add.
