Yes. It's on Debian / Ubuntu, correct?  I have the same issue, and word is
that it should get fixed upstream at some point. It only bites when you call
via texi2dvi though, ie when Sweaving.  So for Rcpp, and directly in the
inst/doc/Makefile, we do the following test for my username -- in which case
we use pdflatex and no ugly tilde symbols creep into whitespace -- or else
use tools::texi2dvi() :

ifneq (,$(findstring edd,$(whoami)))
	pdflatex Rcpp-modules.tex
	pdflatex Rcpp-modules.tex
	$(RSCRIPT) -e "tools::texi2dvi( 'Rcpp-modules.tex', pdf = TRUE, clean = TRUE )"

Hth, Dirk
