There just one version number, and it has to match exactly. (Well, actually, everything after the ".so" is the "version number". It can have lots of digits but they still have to match exactly.) That's just the way it works in the ELF standard. Search the archives of the FreeBSD-current mailing list for way too much discussion about it. > I couldn't find a man page for the runtime linker, too. man ld.so But it's out of date and doesn't describe the current ELF situation accurately.
