adjust the cards settings. However I do not believe the PnP is the 
cause. I used this utility to get int 12 instead of 10.

I had exactly the same error messages, after I cvsupped the source to the 
latest RELENG_2_2. After worlding, these errors started to appear.
Pherhaps I did something wrong, dunno.

Try fixing it with:
cd /usr/src/sbin/route
make clean
make
make install

cd /usr/src/sbin/ifconfig
make clean
make
make install

cd /usr/src/sbin/ping
make clean
make
make install

This will build and install the new static binaries.
At least it did the job in my case :-)
 

Hope this wil solve your problem too!!
