nm prints:

What does

	nm -po /usr/local/lib/libpcap.a | egrep grammar.o

print?

This is the first time I've used nm - the man page says that U means the
symbol is undefined, but I'm not 100% sure exactly what that means?

It means that the symbol is undefined, and there's a reference to it from the file "grammar.o" in the library.
