Sounds like you are really new to Linux. Make your life easier and try to find the RPM packages you need for SuSE 9.3 and install them via YaST.
Try to find the packages you need from rpm.pbone.net
Once you find the packages you need double click them and install using YaST. If you get dependency problems, search for the missing packages.
To make it easiser if you have a bunch of packages, before you install add the directory to YaSTs installation source.
As to compiling from source you need to have the compilers installed. Again use YaST to do this.
