libwrap is only actually *used* in snmpd, which defines the variables
correctly. However, with --with-libwrap, it links the client programs,
snmpget, snmpwalk, others with libwrap as well. Since these don't make
use of libwrap at all and don't define the variables, this fails. I am
going to e-mail the maintainers of ucd-snmp and ask them why they are
being linked with libwrap. If it's not using the functionality there's
no reason for libwrap to even be loaded. For now, perhaps there should
be a patch in pkgsrc/net/ucd-snmp/patches?
