missing symbols. The missing symbols are declared in a header file in the iptables source, but not defined. Perhaps there's a missing dependency here? I'm fairly clueless about the whole thing.
Please attach the entire build log to this bug report.
ugh! It works fine now. I haven't re-sync'd portage since then, but I did compile iptables with USE=-ipv6 just to get the rest of my 'emerge world' finished.

I'm closing as WORKSFORME. If there's some hidden dependency you'd like me to dig for, though, please reopen and post more instructions.
