This requests appears a bit rude to opensource developers who are
offering their free time to support the software. It does not really
show that you have invested any of your own time, before you start
asking for other people's time. Doing this will negatively impact
the responses you will receive.

Debian comes with libreswan, you can just install it using "apt".

If you need a newer version, try unpacking the latest libreswan .tar.gz
and run "make deb". You might need to tweak some options in mk/*.mk to
make things work depending on the library and version availability.

You should be able to google those errors and find previous
correspondence of those errors.
