I quickly browse thought the page you sent and indeed this is the way
to retrieve the shared lib deps. However, debian references packages
name (not lib name). So we are still missing the inverse lookup of
what package provide a particular shared libs. I can't remember which
file list all those (package -> libs reference). I guess one could do
a:

  $ dpkg -S libname.so

Anyone feeling like implementing the patch for deb ?
