Não é possível instalar o módulo CGI

Question

Estou tendo problemas para instalar o módulo CGI no Amazon EC2 Linux AMI. Durante o processo de instalação do CPAN, ele falha.

#   Failed test 'write access to CGItest revoked'
#   at t/tmpdir.t line 30.

Aqui estão os registros de instalação. O que estou fazendo errado aqui?

Answer 1

Eu encontrei exatamente esse mesmo problema hoje (também em um Amazon EC2 Linux AMI). Os testes que estão falhando estão "errados". (eles não eram executados anteriormente devido a falhas conhecidas em "algumas plataformas", mas, por razões desconhecidas, reativados no CGI v3.61, lançado em 2 de novembro de 2012)

Basicamente o script de teste está fazendo "chmod 500" em um diretório de teste (que não tem nada a ver com TMPDIR ou / tmp), então fazendo "-w $ testdir" para ver se o diretório é gravável posteriormente. Mas é claro que o root pode gravar em um diretório 500 sem erros. Portanto, esses testes devem falhar para qualquer pessoa que instale o CGI com privilégios de root.

Pelo que vejo, é perfeitamente seguro:
