Solved error joining network: airportd MIG failed = -4 ((null))

Question

My old PowerBook G4 (DVI) would not connect to the AirPort Express network I created just for 802.11b devices. All I would get is a "Connection failed" dialog and this in the console: airportd MIG failed = -4 ((null))
Turns out the problem was I had selected WPA2 as the only connection option and the 'classic' AirPort card in the PowerBook doesn't support WPA2. Returning to WPA/WPA2 fixed the problem.

I have no such problem. I compiled it again when I read your post. Here's my PKGBUILD.
