The package version is the first one which contained the library with
the correct minor version so that ld.so doesn't complain.  I don't
know how you determine this, but it's specific to the shared library
and you can do it however you like when you build the library package.
dpkg-shlibdeps just looks the details up in the file provided by the
library package.

libc5 is an exception because 5.2.18-2 is the first one that had the
right dependencies &c for ELF conversion.
