The background here is that we are bundling new lenses with
libguestfs, and then trying some hokey magic based on version numbers
to decide whether to use the replacements.  When that goes wrong, we
end up with two lenses and as Pino says Augeas correctly reports an
error and then uses neither of them.

So we want to get away from bundling lenses, but we can't do that
until we can say to distributions "thou shalt use augeas >= X".
