Comment (by iAmInActions):

 Update: using the gcc10 port that has been made for leopard and by placing
 this folder (https://github.com/apple/darwin-xnu/tree/main/bsd/net) into
 /opt/local/include i have managed to successfully build openvpn3. This
 issue is therefore not related to the openvpn3 port directly but rather to
 the dependencies (or shall I say lack there of). Once the gcc10 leopard
 port goes out of beta it would be probably a good idea to add it as well
 as the darwin sources as dependencies for leopard.
