Motorola AP Discovery Tool throwing errors

yeah, yeah, it's a hunk of junk and everyone is more surprised when it works than when it doesn't. but i'm messing around with it and it's throwing the weirdest errors... can't seem to figure out what the heck is going on. if anyone has sorted this out or has a better tool that does the same things, please drop me a line. thanks.

here's the CLI barf when i run DiscoverAPs.exe:

The following Interfaces are associated with this Machine IFACE IP MAC ===== == === eth0 192.168.7.74 <VALID-MAC-HERE> Enter Interface(eth0,eth1,...) from the above list to Discover APs :: eth0 Broadcasting an AP Discover message Traceback (most recent call last): File "DiscoverAps.py", line 189, in <module> File "scapy\sendrecv.pyc", line 357, in srp File "scapy\arch\pcapdnet.pyc", line 313, in __init__ File "dnet.pyx", line 112, in dnet.eth.__init__ OSError: No such file or directory 

aplogies for the self-serving, mass-inflicted torture... :P but thanks for the help.
