Nice catch!
I think libpcap uses bison... in the docs/FAQ file:
Q. I have experienced problems defining multiple filters: ntop reports
'syntax error'. What shall I do?
A. If you believe the filter is syntactically correct then it's likely
that the libpcap you have used has been compiled using an old
non-reentrant version of flex. Please make sure you're using
version 2.5.4 or above.
ntop does ask for yacc|bison - look in the missing file, where it warns you
(but it's only a warning, so perhaps you missed it)...
bison|yacc)
echo 1>&2 "\
WARNING: \`$1' is missing on your system. You should only need it if
you modified a \`.y' file. You may need the \`Bison' package
in order for those modifications to take effect. You can get
\`Bison' from any GNU archive site."

This is a very long shot, but you might be using the flex and bison
replacement for lex and yacc. I believe there are slight differences between
the two, but IIRC (it's been a while) bison has a command line option to
make it entirely compatible with yacc. You might want to check exactly what
you are using and possibly add that parameter.
