Usually there is no named.conf by default - that would be silly, because it needs to have reasonable contents and the Fedora guys can hardly guess what each unique user want to have as a default.
Just create /etc/named.conf as root and define your first zone, even if it's only one for testing.
If you installed bind-chroot (obviously), then you also have to create links from your chroot setup to the standard locations. If you don't want bind-chroot, then uninstall it (either yum or rpm), and produce a standard name server (usual file locations).
Howtoforge has good tutorials on everything Linux, and tldp.org also has the BIND-HOWTO with all the precious details.
