The 'quadprog' pkg is not listed as a dependency or even as 'suggested' and
there is no mention of 'quadprog' in the NEWS file, nor does a search of the
'demos' code for a call to load "quadprog" produce a hit, and there is no
mention of quadprog in the NAMESPACE file, so the message while "clear" can
still be considered "quite unexpected".
