Ncat: socket bind error on Mac OS X

Hi, on Mac OS X 10.5.4 (Intel) Ncat dies with the following error when I try to put it into listening mode: $ ncat -l 22222 bind: Invalid argument Running Ncat as root, switching to UDP or disabling IPv6 in my system preferences did not help. I verified that there is no other process listing on my local TCP port 22222. Apparently the bind() call in sys_wrap.c returns -1 and errno = 22 (EINVAL). According to the man page [1], this means that either the "socket is already bound to an address and the protocol does not support binding to a new address" or the "socket may have been shut down." In client mode Ncat works fine. Any ideas what I am doing wrong or how I can help debugging?
