I wonder what might be wrong > here and how to fix this. If you haven't got this sorted yet, try the attached patch. It also corrects the SONAME of shasta.so. It does mean there's an RPATH in the executable, however. The problem with the previous solution is that it sets the NEEDED value in the executable to the absolute path of the shared library, instead of the SONAME, so it didn't matter what directory was passed, dpkg-shlibdeps wouldn't find a library with the right SONAME.
