Today, a package that has an HTML vignette (but no PDF vignette) failed
R CMD check --as-cran on a system without qpdf. I think the warning
originates here [1], due to a premature check for the existence of qpdf
[2]. Setting R_QPDF=true (as in /bin/true) helped, but perhaps it's
possible to check qpdf existence only when it matters.
I have attached a patch (untested) that could serve as a starting point.
The code links correspond to SVN revision 69500. Thanks.
Best regards
Kirill
