IPv6 scanning problem

I've been trying to use nmap v 3.90 and 3.93 to do a TCP connect scan
of a machine over IPv6. I get these errors:
CONN (0.0000s) TCP localhost > fe80::203:93ff:fe63:9444:80 => Invalid argument
Strange error from connect (22):Invalid argument

The traces from running it with IPv4 and IPv6 are below. 

I tested IPv6 communications between the nmap host and the target
using ping6. I also have ethereal watching the network and I see the
ICMP6 traffic but nothing is seen when I run nmap.

Any help would be appreciated. Thx.
