Configuração do Apache para rodar Python CGI

[hcbravin]

Bom dia pessoal. Estou travando uma batalha a dias e não to conseguindo sair do lugar. Estou tentando rodar Python CGI no meu computador mas não sei onde estou errando, poderiam me ajudar?

Tenho instalado
Ubuntu 14.04
Apache 2
Python
libapache2-mod-python
PHP5

Todos instalados pelo apt.

As configurações são:
(Estou postando no pastebin para não ficar extenso demais aqui.)

/etc/apache2/apache2.conf -> http://pastebin.com/7wcxX1j7
/etc/apache2/sites-avaliabe/000-default.conf -> http://pastebin.com/5tuMCVCz
/etc/apache2/sites-enable/000-default.conf -> http://pastebin.com/aUzFHrJ4

Quando tento entra na pasta aparece isso no navegador:

Forbidden

You don't have permission to access /cgi-bin/ on this server.
Apache/2.4.7 (Ubuntu) Server at localhost Port 80

Quando tento rodar um script .py dentro da pasta cgi-bin aparece isso no navegador:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

Bem, o motivo do erro está aí; agora é corrigir o programa fonte e testar novamente.

PS: Você precisa mesmo de CGI? Pq tem formas bem melhores de trabalhar, tanto em termos de desempenho quanto de segurança...

[hcbravin]

Então o erro está no Script ... Sim infelizmente tem que ser. É um projeto de Pesquisa onde meu orientador quer rodar umas coisas no Google App Engine (GAE), e é encima de Python lá.

De qualquer forma, muito obrigado pela ajuda.

Veja só, o fato de precisar ser Python não quer dizer que precise ser CGI...
