That's the libtool configuration you're describing.  I left the version
convention as it was from the original submitter (John Lam).  Libtool
actually recommends a different arrangement of the numbers (soname) -
which still is not compatible with the convention we've been using for
several years. If there were enough interest in it, I'd add a configure
option to modify the soname - but your problem isn't directed to that.
(In fact, I don't get many questions about libtool - packagers tend to
ignore the configure options if they don't work as expected).

There's more than one way to construct a soname with libtool - its
preferred one has nothing to do with the package version (and in fact
differs from the native convention on more than one machine).  Since the
actual algorithm isn't documented except in vague generalities, it's hard
to compare without reading the libtool script.  (Sure, they tell you how
to set it up, but that's not documentation of the algorithm).

Offhand, I seem to recall that you cannot reliably force libtool to use
the same convention that I've been using for ncurses in the non-libtool
convention, and - as you see - libtool's install method doesn't check for
conflicts.
