The 32 bit libraries are built as part of buildworld/installworld.  
However, if you still have a fresh world laying around, you might be 
able to build just the libraries part like this:
cd /usr/src;
make build32
make install32

If you have any trouble, then do a full buildworld etc and they will be 
included with it.
