Thanks for the pointer... but I ended doing something
different that worked very well...

1) I enabled the Fedora Infra Cloud repo which has
    the jdoss/wireguard repo
       dnf copr enable jdoss/wireguard

2) Then installed the  wireguard-dkms and  wireguard-tools
    packets which brought in the dkms command.
        dnf install wireguard-dkms wireguard-tools

3) Then I simply reboot and mdks compile the module and
    installed it... Very cool!

Thanks again!
