truss -o truss-tmux tmux

In reference to http://docs.freebsd.org/cgi/getmsg.cgi?fetch=203867+0+archive/2015/freebsd-questions/20151011.freebsd-questions and the follow up answers it seems that it is not possible to start tmux on a IPv6-only system.

I attached `truss tmux`. The import line is

> socket(PF_INET,SOCK_DGRAM,0)			 ERR#43 'Protocol not supported'

After adding an IPv4 to the jail where I tried to start tmux, the problem was resolved. Nevertheless, imho, it should be possible to start tmux on an IPv6-only system.

Is this a FreeBSD specific problem ? If not, please open a problem report upstream.

Openned an issue upstream.

(In reply to Mathieu Arnold from comment #2)

Thank you for opening a report upstream.

I was not sure whether it's FreeBSD specific. In the mailing list, someone said  the fact that I built the package on a machine that has both IPv4 and IPv6 might have caused the problem.

No, it builds fine without any ip at all.
I tried with jails that have neither v4 nor v6, and if there is no v4, it fails to run. (v6 being there or not does not matter at all.)
