#65247: OpenVPN3 build fails under leopard

 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.7.2

------------------------------+----------------------
 I have been trying to compile OpenVPN3 on my PowerBook G4 that is running
 leopard. The build gets to 28% and then just fails throwing the generic
 "command execution failed" error.
 Looking into the logs it says that the file net/if_utun.h is missing.
 Running whereis and locate on that file name returns 0 results meaning it
 actually is missing and not just causing a false alarm like with SDL2.

 Any ideas where I could get this file?
