Wouldn't it be easier, faster and more compatible with dpkg to do
something like:

#!/bin/sh

OLDPACKAGES="amsfonts amslatex amstex babel bibtex dviljk dvipsk kpathsea kpaths ea-dev latex latex2e-doc ltxgraph ltxmisc ltxtool makeindex mfbasfnt mfbin mfdcf nt mfnfss ntgclass oldgerman pandora ps2pk psnfss texbin texi2html texinfo texli b texpsfnt textfm xdvik tetex tetexlib tetexdoc"

OLDPACKAGES2="mflib xypic"

echo -en "\n checking for old tex packages "
PACKAGES=`dpkg -l $OLDPACKAGES 2>/dev/null | awk '$1~/^i/ {print $2}'`
PACKAGES2=`dpkg -l $OLDPACKAGES2 2>/dev/null | awk '$1~/^i/ {print $2}'`

[etc]

Am I missing something?
