Hello Rosalio,
Step 3 in that document runs "make" which kicks off the compile stage. This step completely assumes you have a working developer environment with various compilers, linkers, libraries, etc. already installed. If you can tell the group which Linux distribution you're running, there are a few simple commands that will go out and install everything required. Building and packaging Linux software isn't hard and once these dependencies are in place, building other software programs is a snap.
