folks, current wireguard seems not to install or build on RHEL 8.0

(1) via yum and the wireguard repo at
https://copr-be.cloud.fedoraproject.org/results/jdoss/wireguard/epel-7-$basearch/

[root@<>]# yum install wireguard-dkms wireguard-tools
...
Copr repo for wireguard owned by jdoss
          1.7 kB/s | 3.5 kB     00:01
Error:
 Problem 1: conflicting requests
  - nothing provides dkms needed by
wireguard-dkms-1:0.0.20190601-1.el7.noarch
 Problem 2: package wireguard-tools-1:0.0.20190601-1.el7.x86_64 requires
wireguard-dkms, but none of the providers can be installed

and (2) building without much trying albeit -

[root@<> src]# make
  CC [M]  /root/WireGuard/src/main.o

Thanks in advance for hints,
