Issue

Initially I used the following with no success;

export http_proxy=http://username@password:host:port

Worth noting I don't get a connection error directly, instead;

[root@pal ~]# sudo pear info  PHP_CodeSniffer-1.2.1
No information found for `PHP_CodeSniffer-1.2.1'

Solution

Instead of using the system's http_proxy, set the proxy directly in pear's config;

pear config-set http_proxy http://username:password@yourproxy:80
