FreeBSD version LDB_0.9.10 required by /usr/local/samba/sbin/samba not defined

This ones got me flipping puzzled.

I have three 8.1 amd64 servers and an 8,2-BETA amd64 server.  One of 
the 8.1's and the 8.2 run Version 4.0.0alpha14-GIT-6bc6c00 no problem.

Two of the 8.1 boxes, which were running the last update I did ~2 
weeks ago perfectly now say:

zaphod# /usr/local/samba/sbin/samba
/libexec/ld-elf.so.1: /usr/local/samba/lib/libldb-samba4.so.0: version 
LDB_0.9.10 required by /usr/local/samba/sbin/samba not defined

I can't for the life of me figure out what the heck is out of step 
between the two that work and the two that don't.  Any pointers, 
ideas, etc would be greatly appreciated.

Cheers,
