This point does need to be be made clear.  It is vital for the later
sanity of the systems administrator not to simply overwrite package
-managed files with those built by Samba.  Not only can then be easily
overwritten by another well-meaning package or update, a source upgrade
needs a little more care than just 'make install':

By putting the libs under /usr/local/samba or /opt, you can remove the
old binaries before installing new ones.  This is both important and
required, and isn't practical when co-mingled in system paths. 

This does matter, as for example, if we were to rename/withdraw a ldb
module, you would still have the old module, not overwritten by make
install, and (at best) Samba would fail to start.

While less critical, leaving libraries by old names around in system
paths after an upgrade is just asking for trouble. 

Thanks,
