IPPROTO_UDPLITE should be added to <netinet/in.h>...

You have to add implementation of UDP-lite protocol support to kernel.

It looks like that you are trying to *use* UDP-lite with assumption
that it were implemented in NetBSD kernel.

If the code is really you have quoted, you must check return value of
socket() first.

No.  UDP-Lite is similar but different protocol from UDP.  To use
UDP-Lite on NetBSD, someone implement UDP-Lite support to kernel.

Best regards.
