Ughhh... I had a concern this would happen (because iw and aircrack-ng used to conflict... I guess they still do, not sure how to fix that though). What happens if you apt-get install iw first (if it doesn't work by itself, then after uninstalling aircrack-ng first, the install iw, and then trying to install aircrack-ng again)?

- Edit -

AND there's a dependency on zlib1g for some reason... *Facedesk*(Edit 3: apparently that's supposed to be there for aircrack-ng 1.1, and it's not a bug. Cool, less work for me.)

- Edit 2 -

I figured it out (by manually getting the deb on my N900 and using dpkg --simulate -i on it) - it's iw that conflicts with aircrack-ng... Okay, I'll remove the iw dependency on the aircrack-ng end and then annoy the maintainer of iw to get rid of the conflict on his end.
