'sendto' error in OSX 10.1.5

I had been working with Nmap 2.54BETA30 on the command line since installing OSX 10.0.x last year without any known issues. Shortly after upgrading to 10.1.5 and adding the last few security patches, Nmap started returning "permission denied" errors from calls to 'connect' and 'sendto'. I compiled and installed Nmap 3.00, but got the same results. Ditto when logged in as root. I haven't seen mention of anyone seeing this boo-boo on Google or the list.
I see where the error pops up in the code, but I don't know why 'sendto' is returning an error. Has someone got a clue I can buy as to a direction to investigate? I've gone so far as to set the directive TCPIP_DEBUGGING and arguments -v -v -d, but the results aren't telling me anything.
Attached for lack of clue: short form outputs from TCP and SYN scan, loooong form from SYN...
