What I had found in the past is that the port (more exactly
ipsec-tools) does not complain if configure is run with
--enable-natt but the correct header files are no there. It silently
continues and just disables natt support.
That beahvior would be fine for "autodetect" but not for a command
line option that says "I want natt support and you give me".
