What I have found is several dependencies for asl-asterisk are missing. I was able to install everything but libcurl3 there is probably a dependency that asl-asterisk needs that uses libcurl3. I think we might have to add a symbolic link from libcurl3 to libcurl7.*
Or dig deeper into the asterisk code and compile it for libcurl7.*
Or maybe the code geniuses can whip up a not so quick fix
