Problem with package development

Okay, that might have been a little strong.  "screams bloody murder"
is a warning, not technically an error, and does not occur when simply
running R CMD build.  That said, the OP did mention using R CMD check
and pdflatex is not an issue when only building anyway.  Still, it is
not the cause of the earlier problems and I was probably overly harsh
and I give my sincerest apology.
