line 101/102 of the module passes the output of gethostbyname(hostname)
straight through to inet_ntoa,
which produces this error message
"Usage: Socket::inet_ntoa(ip_address_sv) at
/usr/local/share/perl5/Net/Syslog.pm line 101."
if the name to ip resolution did not succeed (eg. temporary dns outage,
no /etc/hosts entry) as gethostbyname
returns an empty array in that case.
i think the simplest workaround for this would be to fall back to use
the unresolved hostname straight; rfc3164 does allow either hostname or
ip address (section 4.1.2).
