Okay ... I got a couple of questions about this:
1) Why? There is sysutils/pftop ready for the taking
2) Why 6.0?  It's EOL'ed (esp. in the pf department)
3) Why?!?

There's your problem right there.  You need to set the OS_LEVEL in the 
Makefile in order to compile successfully.  See the aforementioned port's 
Makefile for sensible values depending on __FreeBSD_version.

^ ... simply use the port.  Be advised, however, that the port fails to build 
on recent CURRENT due to the libpcap 1.0 update - workaround patch for that 
problem is attached, a proper solution should hit the tree over the weekend.
