The problem is that the automatically-generated Makefile.in that comes
with Phil Wood's version of libpcap is broken - it does *NOT* supply an
argument of "-Dyylval=pcap_lval" when compiling grammar.c into
grammar.o, and therefore grammar.o refers to "yylval" while scanner.o
refers to "pcap_lval", resulting in an unusable libpcap.

That causes the "pcap_lval" errors; the other errors are caused by the
configuration script being screwed up by "pcap_lval" errors.

Try adding the line

        #define yylval pcap_lval

after

        #ifdef HAVE_CONFIG_H
        #include "config.h"
        #endif

in the "grammar.y" in Phil Wood's libpcap and rebuilding libpcap.  Then
go to the tcpdump directory, do "make distclean", re-run the configure
script, and rebuild tcpdump.
