google到了这篇文章（http://www.vpsee.com/2011/07/how-to-use-git-through-a-http-proxy/），说git只有用HTTP方式的时候能使用代理，其他就只能找使用socat这样的代理软件了，connect-proxy大概也可以……
但我琢磨我这样可能更标准也更简单一点：
1、查到服务器ip
wangjl@wangjl-laptop ~/workspace/test $ host git.savannah.gnu.org
git.savannah.gnu.org has address 140.186.70.72
2、建立ssh通道
ssh -L9418:140.186.70.72:9418 -i ~/.ssh/vpsee xxx.xxx.xxx.xxx -pxxxx （呵呵，我也是vpsee的客户）
3、修改hosts文件
echo 127.0.0.1 git.savannah.gnu.org>>/etc/hosts
效果：
wangjl@wangjl-laptop ~/workspace/test $ sudo emerge -av gnulib

vpsee的机器还是挺快的
