Can not use 'wget' download file through proxy in Ubuntu

I am trying to

$bitbake omap3-console-image

I got 'wget' errors.

I have already setup the proxy in my Ubuntu to be:
http_proxy = http://10.0.x.x:port/
ftp_proxy = http://10.0.x.x:port/

But it still does not work. The reason is that Ubuntu does not look at the proxy setting when use wget.

Here is the solution:

Take a look at .wgetrc or /etc/wgetrc and define there your proxy server.

Done!
