Thanks Eric. Yes, even though I thought I'd checked all the available
export options, I failed to distinguish the nuances between p and P. Your
initial answer pointed me to the right direction, as I found that pdflatex
on the exported tex would give a different pdf from the export command (C-c
C-e l p). Now one more step closer to the destination, if only I can figure
out how to get the missing title and author in the pdf.

Thanks for all the help!
