I don't think Simon did it just for fun... I think this part of that 
handbook is more telling...

        "That is, if you link with libfoo.so.3.3.3, the linker only records 3.3 
in the headers, and will link with anything starting with 
libfoo.so.3.(anything >= 3).(highest available)."

That means that if one links to *.so.1.31.0, the FreeBSD linker will try 
and link to *.so.1.32.0 if available. Personally I'd say the linker is 
broken in this respect, as it doesn't follow the historical 
major.minor.patch where only patch revisions are compatible use. And 
Boost is certainly not the only library follow this so I can only 
imagine the havoc this causes all around.
