Hello Benjamin,
You should try installing nconf (a web interface for nagios configuration)
instead of doing it from CLI.It'll save you a lot of headache
You can find how to install it in this
document.http://bmo.kenet.or.ke/index.php/Nagios_on_FreeBSD%C2%AE_7.2
It's quite straight forward there but you can always post any problems.
