Comment:
Setting `<=` a high revision number is a bit hacky, but probably less horrible than the alternatives, which would be either hacking out a `next_version` variable so we could do `libmpg123>=${version}<${next_version}` (which would be fragile) or just dropping the `<=` (which might break some people's systems on upgrade). Done.
