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.
