Please help me build blender. I'm having a bit of trouble.

My first question: i am not online at home, i have to use the local library to get stuff to my computer.
Do i need TortoiseSVN-, or is this simply a means of downloading, for example, this: and these . i think.

Basically what i am doing now is going through this page by page saving everything.
Please, somebody stop me if i am wasting my time.
