I have been using net-wireless/kismet-2004.04.1 for over a month now with no major issues. Time to unmask for x86?
I've added net-wireless/kismet-2004.04.1-r1 which fixes a missing DEPEND on libwww-perl and updates the used ethereal version. If it proves stable within a few weeks it will be marked x86.
This was fixed long time ago.
Closing as FIXED.
