I think this happens when you R CMD build, not when you INSTALL.

Writing R Extensions tells us:
"The ‘BuildVignettes’ logical field can be set to a false value to stop 
R CMD build from attempting to rebuild the vignettes, as well as 
preventing R CMD check from testing this. This should only be used 
exceptionally, for example if the PDFs need large figures which are not 
part of the package sources."
