This is really great work !!  Thank you.  This is the neat solution I
was looking for.  I'm going to wait for Ken to bump libraries versions
in RELENG_6 and for you to MFC this before upgrading my RELENG_5.

I'm not sure to follow you here.  I saw that current library names are
contained in /etc/mtree/set.base, but I don't see where it is used

OTOH, I check /etc/postinstall too, especially the obsolete_libs()
function, it appears that it returns the name of all .so except the one
with the greatest version number.
