No we're not dead. We just have only a handful of people committed to continuing work on the project right now and pretty much every one of us is busy with other things in our lives.
Are you trying to install the latest trunk build, the latest official release (which is well over a year old), or the latest unofficial release? If you're installing the latest official release, I believe you need Luabind 0.8. The latest unofficial release and trunk both migrated to Luabind 0.9 if I remember correctly. I know that we've had some issues with Ubuntu before because they don't update their Luabind packages as quickly as Debian does. I run Debian unstable which has the Luabind 0.9 package. Worst case scenario is that you'll have to build the Luabind library yourself. Yes, the library is a constant thorn in our side for the build process and compatibility, but it works excellent once you actually have it built successfully.

Our debian packager is ettin and he's usually idle in our IRC channel. You might want to try to get in touch with him if you're having issues with the package, although I haven't heard from him in months. Hope this information is a good start for you. Let me know if that helps or if you have any more questions. Oh and BTW, there's a large difference between the latest official release and the latest unofficial release (there's no Debian package for the later); They are practically two different games. So if you're new to Allacrost you may want to give both of them a try. Thanks!
