one thing i'd recommend doing BEFORE the 1st thing in that tutorial is to go to your setups directory..

ie: /root/setups or a lotta times /var/usr/src or /var/usr/local/src

THEN do what it says.. that way you keep all the downloaded stuff in one place instead of into whatever directory you login to..

to change directory, use the 'cd' command... so to go to /var/usr/src dir.. 'cd /var/usr/src' would do it..
