Uwe& others,
This is OK if you want to identify the cause of the problems. However,
the basic problem was that checking required something that is not
required: there was one example that was not run, and one case where the
loading of the package was not necessary (if(require(<package>))). I do
believe that handling this kind of cases is difficult in automatic
checking. However, I think they need not be checked: there should be a
new case of package reference in addition to 'depends', 'suggests' and
'enhances' -- something like 'benefitsfrom'.
Users use those declarations when they ask to install dependencies. If
you don't declare a dependence on a contributed package, users will have
to manually install it.
This is now actual to me, since I'm adding 'parallel' support to my
package, but there seems to be no clean way of doing this with the
current checking procedures. I use the 'parallel' support only if the
package is available (in R>= 2.14.0, not yet released), and there are
multiple cores.
Temporarily maintain two releases of your package: one for R < 2.14.0
that doesn't mention parallel, and one for R >= 2.14.0 that does. The
second one should declare its dependence on R >= 2.14.0. If support for
parallel is your only change, you don't need to do anything for the
previous one: CRAN will not replace it in the 2.13.x repository if the
new one needs a newer R.

If there is only once cpu or there is not yet
'parallel' package, nothing bad will happen: things will only work like
they worked earlier without 'parallel' package. I haven't found out how
to do this cleanly for R CMD check (it is clean for my code since there
the usage is checked). If I add "suggests: parallel" I get R CMD check
error for the current and previous R -- for no reason. So currently I
don't mention 'parallel' at all in DESCRIPTION: I get a NOTE and
Warnings ('require' call not declared, no visible definitions), but this
is a smaller problem than having a spurious failure, and failing to
have this package for a system where it works quite normally.
The new DESCRIPTION keyword could be used for packages that are useful
but not necessary, so that the package can be quite well be used without
these packages, but it may have some extra options or functionality with
those packages. This sounds like a suggestion to me, but in R language
suggestions cannot be refused.
