Você pode tentar:
sudo cpan App::Ack
Ele instala o ack e configura o binário em /opt/local/bin/ack com o ambiente perl padrão em sua máquina. Após a instalação, você pode simplesmente executar o "padrão ack" e está pronto.
Estou tentando instalar o p5-app-ack port do Mac Ports, mas parece que ele não cria um binário /opt/local/bin/ack no final:
$ sudo port search *app-ack
