I don't recall (and haven't googled the archive) whether we discussed
using alternatives as a mechanism that could default to newest .so but
be toggled to older versions as required...This would allow
side-by-side installation of the -dev packages.  For buildfarm use, it
could be a little unpleasant if it's switched for building one package
and then affects other users.  That might be reason enough to discard
the idea.

The less we have in special-prefix areas the better, as far as I'm
concerned.  If we do this, we'll need to tackle (as a separate item)
the header files, etc too.

Thanks
