make и make install прошли успешно.
Но для самосборной версии нужно:
- сделать конфиг
- создать скрипт запуска в /etc/init.d/
Конфиг: (/etc/pgBouncer/pgbouncer.ini)

Для автозапуска сделать файл pgbouncer gj пути /etc/default/ с содержимым:
START=1
Теперь подключатся нужно к порту 6432 (Он, кстати, стал стандартом...).
Вобщем у меня всё заработало.
Для просмотра диагностики pgBouncer`a
sudo psql -p 6432 pgbouncer -U postgres
Список команд - тут.
Для затравки:
show help;
show pools;
show clients;
