Mac FLAC 2.1.2

Question

I downloaded Mac Flac 2.1.2...went through fine but wants to put binaries in /usr/local/bin and my Mac OS 10.4.8 installatiion did not have a /usr/local/directory. I found some advice to do the following:
open terminal
cd/usr
sudo mkdir local
cd local
sudo mkdir bin
sudo mkdir lib
I am new to my mac and don't know what to do with this. Can someone explain this in simple terms for this simpleton. Thanks EPG.

open terminal
Click anywhere on your Desktop background; the word "Finder" should appear just to the right of the Apple symbol on the upper-left corner of your display. Somewhere to the right of "Finder", the word "Go" appears; click on that. Click "Utilities" from the drop-down menu; a new Finder window will appear, listing a number of utilities. Find "Terminal" within that window, and double-click on it.
cd /usr
sudo mkdir local
cd local
sudo mkdir bin
sudo mkdir lib
These are commands you type in the Terminal window, ending each with the "Enter" key. The prompt that appeared when you first opened Terminal will be re-printed after each command is completed.
After each 'sudo' command, you will be prompted to enter a password; type your login password followed by the "Enter" key.
When you're done, type "exit" (followed by the "Enter" key -- an amusing contradiction, I know); then you can exit Terminal (either from the Dock icon or the Application menu).
