另一種 NOIP0 安裝方式

	Install noip2 from source

	cd /usr/local/src/
	wget http://www.no-ip.com/client/linux/noip-duc-linux.tar.gz
	tar xf noip-duc-linux.tar.gz
	cd noip-2.1.9-1/
	make
	make install

If you get make not found or missing gcc
then you do not have the gcc compiler tools on your machine.
At https://help.ubuntu.com/community/InstallingCompilers
you can find install instructions if you need help.
