If you don't have pcap_open(), you probably don't have remote support, which is why it's required.
I suppose it isn't "sufficient" in the sense that one could, in principle, build a version of libpcap that has pcap_open() but that only supports local capture, but that's rather unlikely.

That's the universe's way of telling you that perhaps, sometimes, you should trust that autotools knows what it's doing, and not try to hack around it. :-)
