Hmm...but isn't the version number also something that can be stored
in the shared library itself during link time (e.g., via the -soname
option to the linker)? The manpage for ld under Linux implies that
this will cause the executable that's linked against the shared object
to look explicitly for a library with the soname specified by the
shared object. I don't know if that just causes the dynamic linker to
look for a file with the specified soname or if it will actually
examine the shared object under consideration to make sure it has the
DT_SONAME field in question, however.
