[Bioc-devel] workflow builder error: winbuilder1 says "pdflatex is not available"

hi,

I pushed a change to rnaseqGene workflow and only winbuilder1 had a
problem:

* checking PDF version of manual ...Warning: running command
'"C:/Progra~1/R/R-3.4.0/bin/x64/Rcmd.exe" Rd2pdf  --batch --no-preview

had status 1

This typically indicates Rd problems.

Hmm ... looks like a package
Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet,  :
  pdflatex is not available
Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet,  :

Error in running tools::texi2pdf()
