samhain - starts on boot?

[fadeaway at gmail.com]

I am running 5.3. I decided to install samhain through ports... 
Afterwards I messed around with it running it -D mode for a bit, I 
killed the process...
Never really bothered with it again but I have noticed that it will 
start on boot without any indication of it in rc.conf or rc.conf.local

Why?
Did me running it in -D mode that one time make it add some startup 
script or when it installed it added it's own startup script?
