instalando falhas do compositor. Não é possível acessar http: //

Question

Estou tentando instalar o compositor com o comando:

curl -s https://getcomposer.org/installer | php

E estou recebendo este erro:

PHP Warning:  Directive 'safe_mode' is deprecated in PHP 5.3 and greater in Unknown on line 0
#!/usr/bin/env php
Some settings on your machine may cause stability issues with Composer.
If you encounter issues, try to change the following:

Your PHP (5.3.2-1ubuntu4.18) is quite old, upgrading to PHP 5.3.4 or higher is recommended.
Composer works with 5.3.2+ for most people, but there might be edge case issues.

Downloading...

The download failed repeatedly, aborting.

Alguma ideia?

Tente atualizar seu pacote PHP primeiro e tente novamente.

parece que algumas extensões do php estão faltando no seu final, aqui está o que eu instalei no meu final:
