it's actually your logging program which is supposed to create /dev/snort_alert
file, when unsock logging option is used, snort just tries to connect there.
if uppon startup of snort /dev/snort_alert doesn't exist, snort will complain about it:
void OpenAlertSock()
    char *srv = UNSOCK_FILE;

    if(access(srv, W_OK))
        ErrorMessage("WARNING: %s file doesn't exist or isn't writable!\n", srv);

Anyway as soon as your 'logging' program creates /dev/snort_alert and start 'listening' to
datagrams from the socket, all logs will be there. It was _AGES_ ago since last time I played
with that, but if you need a sample code - let me know :)

BTW, I wonder what code you were quoting, the code in log.c which is a part of snort, doesn't have
bind :)
