i)   No external noweb package is needed
ii)  Synaptic is not used to install CRAN / CTAN packages
iii) Everything should be provided by r-base-core and tetex-extra.

Since relatively recently, a 'Sweave' command has been added.  So simply do

	$ R CMD Sweave example-1.Snw 
	$ pdflatex example-1.tex
	$ kpdf example-1.pdf		# or xpdf, or gv, or ...

You simply make your life too complicated when Debian and Ubuntu make it
easier for you :)

The r-sig-debian list is appropriate for problems with Debian / Ubuntu.

PS  I usually use simple shell wrappers like this one. Others prefer
Makefile. 


edd at basebud:~> cat /home/edd/bin/sweave
#!/bin/bash -e

function errorexit () {
    echo "Error: $1"
    exit 1
}

function filetest () {
    if [ ! -f $1 ]; then
       errorexit "File $1 not found"
    fi
    return 0
}


if [ "$#" -lt 1 ]; then
    errorexit "Need to specify argument file"
fi


BASENAME=$(basename $1 .Rnw)

RNWFILE=$BASENAME.Rnw
filetest $RNWFILE
echo "library(tools); Sweave(\"$RNWFILE\")" \
      | R --no-save --no-restore --slave

LATEXFILE=$BASENAME.tex
filetest $LATEXFILE && pdflatex $LATEXFILE

PDFFILE=$BASENAME.pdf
#filetest $PDFFILE && acroread $PDFFILE &
#filetest $PDFFILE && xpdf $PDFFILE &
filetest $PDFFILE && kpdf $PDFFILE &
