Solving an "wireless tools not found" error from airmon-ng tool I am trying to use airmon-ng on Lion, but getting this error msg. 

$ sudo !!
sudo airmon-ng 
Wireless tools not found


I installed aircrack with ports. I heard it is possible to use it with lion, but cannot find a solution for the "Wireless tools not found" problem. 

Also, used KisMac as an alternative, but it seems to hang after fetching some packets (~50000).
Unfortunately, airmon-ng is not working on OS X, you will probably have to use a virtual PC with a linux OS + USB WiFi dongle. From FAQ:

Is Mac OS X supported?

The aircrack-ng suite has limited Mac OS X support. Currently it only supports the following tools: aircrack-ng, packetforge-ng, ivstools and makeivs. Any program which requires opening a wireless interface is not supported.
