I think that the PDF file is built during R CMD build, not (only) R CMD
INSTALL. At the very least, the source package currently on CRAN
contains both the *.pdf and the *.ltx files under inst/doc:
https://github.com/cran/cpop/tree/master/inst/doc

Does it help to pass the --compact-vignettes=gs+qpdf argument to R CMD
build? It seems to be off by default.
