Estou tentando instalar a biblioteca GD para perl há muito tempo. Eu tentei todas as pequenas coisas que pude encontrar nas internets, mas nada. Estou tentando obter gráficos do Circos que exigem o pacote GD.

Quando tento instalá-lo através do CPAN, ocorre o seguinte erro:

Tentei reinstalar as bibliotecas jpeg com as opções --enable-shared --enable-static, mas também não ajudou. Também instalei uma versão do perl do MacPorts, pensando que eu poderia ter atrapalhado a instalação do perl que acompanha o meu mac. Alguém tem alguma idéia de por que isso pode estar acontecendo?

(sim, sou relativamente novo no mundo dos terminais e tudo isso e ainda estou tentando navegar por aqui)

Obrigado
