Yes. I've seen the error on Gentoo and CentOS 6.x. Both times the
software was compiled on the very same machine. Maybe "SO_REUSEPORT" is
defined somewhere when it shouldn't.

I see that other software that uses "SO_REUSEPORT" uses a
"probe-at-runtime" approach (example: Unbound DNS Server): if it works,
use it, if not, keep going without it.
