Shy Suggestion?

I think this needs to fail because packages listed in 'Suggests:' may, for 
example, be needed in the examples.  How can 'R CMD check' run the examples and 
verify that they are executable if those packages are not available?  I suppose 
you could put the examples in a \dontrun{}.

Yes, that's what I do, and exactly for that reason: if something is not
necessarily needed (= 'suggestion' in this culture), it should not be
required in tests. However, if I don't use \dontrun{} for a
non-recommended package, the check would fail and I would get the needed
information: so why should the check fail already when checking
DESCRIPTION?
