If the problem is an incompatible stat, then a workaround is to change the highlighted line in the 4.5.9587.sh scipt, from:

for F in $FILES_TO_PATCH; do
    echo "Patching $F ..."
    mkdir -p `dirname $NEW/$F`;
    $PATCH32LSB_BIN -p $SOURCE_DIR/`basename $F`.patch -i $OLD/$F -o $NEW/$F;
    chmod `$STAT $OLD/$F` $NEW/$F;
done

to:

for F in $FILES_TO_PATCH; do
    echo "Patching $F ..."
    mkdir -p `dirname $NEW/$F`;
    $PATCH32LSB_BIN -p $SOURCE_DIR/`basename $F`.patch -i $OLD/$F -o $NEW/$F;
    chmod 0755 $NEW/$F;
done

Edit: I might make this change in the next version anyway, since all the files we are patching have the same permissions.
