Check to see if the man package is installed with this command: rpm -q man.
The man package displays the man pages of installed packages, one of the features of rpm is that you can exclude documents when installing a package/packages which includes the man pages, so the man package can actually be installed and configured correctly but can't format the documentation if it does not exist if it was excluded during installation.
I have not installed Fedora 8, but long ago did install Fedora Core 6 and Fedora 7. I believe you can select whether to install documentation or not during installation when selecting package groups.
Open your graphical package manager and check if the documentation group is installed, it can be installed from there if not.
