Regarding the libxau0 problem, this seems to stem from using the same package for the 770 as for the N800. libxau0 is a package that is provided on the 770 by default, but is not provided on the N800, presumably because it isn't necessary anymore. The vncviewer package has a dependency on libxau0 (which is itself a product of the build environment), even if it isn't needed when running vncviewer on the N800, and that seems to be the source of the problem. I think that some users have been able to install vncviewer because they have set their repositories up to download libxau0 from one of the 770 (mistral or scirocco) repositories, but this shouldn't be necessary.

Instead, I downloaded and installed the new development environment for building software for the N800, and I am going to use this environment to create a package specifically targeted to the N800 (bora, or maemo 3.0). I will hopefully have a new package for N800 users some time tonight or tomorrow. And, it will be simple to install--just open the .install file and it should work. However, I don't have an N800 on which to test this--the best I can do is test it in the N800 development environment, but this isn't quite the same as testing it on the actual device.

In addition, I am working on some additional enhancements after spending some time using VNC viewer that I hope you all will like. So, the next release will likely be 0.5.1.
