Actually, I did get a full set of debug-style error messages.  And,
indeed, one system is running an old Ubuntu.  So I'm glad that you
mentioned that, so I no longer think that r-b doesn't know how to emit a
simple warning line.

The collections which cover multiple versions of Ubuntu (and whatever
similar ones might exist for other distros) should be documented
someplace.  Probably at least in a Wiki page about version level
compatibility, so there will be a place for present and future
compatibility notes.
