halo........ i had downloaded iproute2, iproute2-051007.tar.gz from http://developer.osdl.org/dev/iproute2/download/

I did tried to follow the instruction of compiling from this link: http://www.policyrouting.org/iproute2.doc.html

But , when i typed "ip addr" or "ip addr list" there is a error message said that the ip command not found shown in terminal :

bash: ip: command not found



Below are the message shown when i folllowed the 8 steps compilation instruction of above link :
