This is your error.  strace would tell you what's going wrong here.  On
a working server you should see a sequence like:

socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 1
getrlimit(RLIMIT_NOFILE, {rlim_cur=1024, rlim_max=1024}) = 0
setsockopt(1, SOL_TCP, TCP_NODELAY, [1], 4) = 0
setsockopt(1, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(1, {sa_family=AF_INET, sin_port=htons(6001), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
setsockopt(1, SOL_SOCKET, SO_LINGER, {onoff=0, linger=0}, 8) = 0
listen(1, 128)                          = 0

Most likely one of the calls to socket(), bind(), or listen() is
failing; figure out why.
