Re: compiling gnunet 0.16.3 on openbsd

[Nikita Ronja Gillmann]

Hi,

PK_PKTINFO with a quick search seems to be implemented in NetBSD (turns 
up on my system, never ran into this issue) and FreeBSD.
OpenBSD had discussions in 2001, and fast-forward to 2016 it is not 
implemented according to the Changelog of their usr/sbin/unbound:
https://github.com/openbsd/src/blob/master/usr.sbin/unbound/doc/Changelog#L4522

Maybe this also holds a solution on how to solve this for gnunet.
