3.1. Stuff you will need
Basically, you need two different things: software that is already running on your machine (eg., pre-installed by your distribution) and packages 
of source-code for different programs.
3.1.1. Software you will need
- a running gcc 
- an older version of glibc ;-) 
- GNU-binutils 
- GNU-make 
- the GNU-core-utils 
- GNU-tar 
- bash or any shell you prefer 
- very useful but not a must: Midnight Commander 
- an editor you like (vi, jed, etc.) 
3.1.2. Sources you will need
