I haven't had any trouble installing apps with 2006.49-2

Dropbear was one of the first I installed after upgrading. I had version 048-0.1 stored on my memory card, and it installed with no complaints.

I also re-installed all my favorite apps from various repositories. I think I only ran into trouble when I tried to install "less." Again, that one was on my memory card and I haven't looked into whether there's a new version out.
