There is no actual "urchin" as far as I know.  The control file is 
/usr/local/urchin/bin/urchinctl.  It is a executable file:

urchin# file /usr/local/urchin/bin/urchinctl
/usr/local/urchin/bin/urchinctl: ELF 32-bit LSB executable, Intel 80386, 
version 1 (FreeBSD), statically linked, stripped

After running "/usr/local/urchin/bin/urchinctl start", I have these 
related processes:

urchin# ps acux | grep urchin
root    70937  0.0  0.0  3184  1996  ??  Ss    7:00PM   0:00.01 urchinwebd
nobody  70938  0.0  0.0  3184  2000  ??  I     7:00PM   0:00.00 urchinwebd
nobody  70939  0.0  0.0  3184  2000  ??  I     7:00PM   0:00.00 urchinwebd
nobody  70940  0.0  0.0  3184  2000  ??  I     7:00PM   0:00.00 urchinwebd
nobody  70941  0.0  0.0  3184  2000  ??  I     7:00PM   0:00.00 urchinwebd
nobody  70942  0.0  0.0  3184  2000  ??  I     7:00PM   0:00.00 urchinwebd
nobody  70944  0.0  0.0  1460   720  ??  Ss    7:00PM   0:00.03 urchind
nobody  70946  0.0  0.0  1332   668  ??  Is    7:00PM   0:00.51 urchind

And conversely, "/usr/local/urchin/bin/urchinctl stop" removes all of 
the above processes.

Thanks,

Drew
