[netflow-tools] "Fatal error - exiting immediately"

[Tony and Robyn Lewis]

Have just come across softflowd, and am trying to get it working.

When I run it, i get a fatal error:

me at mymachine:~/softflowd-0.9.7$ sudo ./softflowd -i eth0 
-nlocalhost:2055 -d -D
softflowd v0.9.7 starting data collection
Exporting flows to [127.0.0.1]:2055
Fatal error - exiting immediately
Exiting immediately on user request

I had a quick poke in the code, but nothing jumped out.  I can see where 
the error is reported, but it looks like it's generated in the big 
for(;;) loop.

I'm using libpcap0.8 headers, though I tried it with libpcap0.7 too.

The following tail end of strace output might yield clues:

My eye is drawn to the lines:

recvfrom(3, 
"\0\220\32\240\0\320\0\2\245\254\222C\210d\21\0\10\242\5"..., 160,

pkttype=PACKET_OUTGOING, addr(6)={1, 0002a5ac9243}, [20]) = 1462
ioctl(3, SIOCGSTAMP, 0xbf9ea5f8)        = 0
write(2, "Fatal error - exiting immediatel"..., 33Fatal error - exiting 
immediately) = 33

But other than that, before I go flinging code hither and yon, am I 
missing anything glaringly obvious?

I'm running debian testing, on a PIII jobbie.
