Задать переменную $COMPOSER_HOME для composer

Я хочу установить проект на free-хостинге, нет ssh.
Вот проект(скачал, закинул): https://github.com/Gemorroj/gmanager
Вот консоль с помощью которой я пытаюсь воспользоваться composer-ом: https://github.com/antonmedv/console/blob/master/console.php

s210244$ php composer install
