Try running:
	cd /usr/src/share/mk; make install
	cd /usr/src/lib/libpcap ; make clean && make && make install
after you've updated the sources in those directories.

The method in which libpcap's lex & yacc sources are parsed was modified,
but there was a window of a day or so where this wasn't working correctly.
