Hi Paul,

The truth is, we haven't figured out all of the intricacies of recent
changes to R and R CMD check related to these warnings.  I'm not even
convinced of the utility of checking that Bioconductor packages can be
loaded without default packages.  Yes, it _should_ work, but this is a
rare use case AFAICT.

And now after responding to one developer that they should avoid calls
to require() in their code, I'm going to send you a patch that does
just this :-\

Anyhow, for me the following patch seems to fix the warnings and more
or less make sense to me.  While I'm at it, I have two comments:

1. The status message from .onLoad that prints out 'First.lib' is

2. <code_police=ON> You are among a fairly small crowd writing func
   (args) instead of func(args).  Just because you can be different,
   doesn't mean you should be</code_police=OFF> -- its your package,
   suite yourself, but it hurts my eyes [I'm sure my code is equally
   painful for you to look at] ;-)

Here's the patch:
