I dunno. Send me a compatible gps unit please. Thanks!

Whenever you get missing dependencies errors, you should report the exact dependencies which are missing.

> apt-cache show kismet

Package: kismet
Version: 2007.01.R1b-1.0
Priority: optional
Section: user/net
Maintainer: Cezary Jackiewicz (email) <cezary the (4t) symbol eko.one.pl>
Depends: libc6 (>= 2.3.5-1), libgcc1 (>= 1:3.4.4), libncurses5 (>= 5.4-1), libpcap0.8 (>= 0.9.3-1), libstdc++6 (>= 3.4.4), ncurses-base
Architecture: armel
Filename: dists/mistral/user/binary-armel/kismet_2007.01.R1b-1.0_armel.deb

Those are the dependencies my installed kismet lists.

Look at the application manager error log (it's available via the menu) to find exactly what dependency is missing.

Then contact the maintainer (email listed above) and ask him to include the required dependencies in the kismet repository, or remove unneeded dependencies from the control file.
