easy_install will not connect through proxy

I'm running Ubuntu Server 10.04 64-bit under VirtualBox, and it seems that everything except easy_install and pip can connect to the Internet. I have set and exported the http_proxy environment variable, and also set up the proxy address in every other location I'm aware of. Yet easy_install always returns "Network is unreachable": :~$ echo $http_proxy http://192.168.1.25:80/ :~$ grep "http_proxy"
