You need to install kernel-devel and kernel-headers packages which should be on the DVD/CD's. To do so, navigate to Fedora/RPMS directory on the disk from in a terminal, type:
To see all packages starting with the name "kernel", install the kernel-devel and kernel-headers packages matching the name of your kernel with rpm install command as such:
Use the full name of the package right down to the .rpm extension. To see exactly which kernel is installed, type: uname -r in a terminal. If rpm gives an error saying there are missing dependencies, it should also tell you what packages are missing, you need to install those first. You need some development packages like: gcc, gcc++, etc.

Is postgres up and running to begin with?

ps -ef | grep post

Was it told to listen on any interfaces?
grep -i listen /path/to/postgresql.conf
