Aha!  The location of libtalloc.so has changed from {prefix}/lib/ to 
{prefix}/lib/private/.  I was installing on top of the existing v3.6.25 
directory, /private/samba/.  The old libtalloc.so was still in 
{prefix}/lib/.  When I install to a new directory, without the old 
libraries, run-time linking is working correctly.

What is the recommended way to "upgrade" Samba but preserve the 
configuration?  In the past, I've been able to install over the top of the 
existing installation, but I think I'll need to do a clean install this 
time.

I think I need to preserve:

lib/smb.conf
private/*
var/*

Any advice you can provide is welcome!

Thanks,
