Unlike FreeBSD, Fedora Core doesn't install a compiler as default. You need a compiler to run commands make when installing stuff. If like me, you omitted to request the compiler during the FC3 install, then it has to be done manually.
The problem with installing the GCC (Gnu Compiler Collection) is that it has many package dependencies which quickly get very tiresome. I prefer to use yum. Make sure your internet connection is working and run the following command..
yum install gcc
Sit back and marvel at yum doing its stuff. Too easy!
