I think this is a little bit outdated. We only have one number after  
the .so since a long time. All libs in /lib and /usr/lib are .so.X and  
for 3rd party applications most are .so.X (those which aren't are a  
sign of bugs in the ports collection). On one of my systems 1.2% are  
not .so.X:

---snip---
% ls -1 | grep .so. | wc -l
      539
% ls -1 | grep .so. | egrep '\.so\.[0-9]\.[0-9]' | wc -l
       7

No. Those FreeBSD versions which used a.out instead of ELF are not  
supported anymore since a very very long time. We still are able to  
load a.out stuff in the current releases, but the entire compiler  
toolchain is using ELF by default. You have to make some effort to  
generate a.out stuff.

Bye,
Alexander.
