Startup messages

Hi there,

As I got conflict error messages when installing nocat from ports, I decide to 
do a manual installation with pogozone patchs (ipfw2 and radius).

One thing have to be notice that pf already include into FBSD 5.3 base 
installation file. There for need to make some changes on detect-fw.sh with 
exclude line 34-36. Otherwise the installation will pick pf as a default 
firewall utility.

After finish with installation (I did same box installation for auth and gw 
functions with different directory), I got the following messages :
ipfw: setsockopt (IP_DUMMYNET_CONFIGURE): Protocol not available

The above messages displayed about 8 lines.

What could be wrong ?
Should I recomple kernel and or ipfw ?
If so, where can I find the guidance to do it ?

Regards

PD
