if [ \( "$1" = "upgrade" -o "$1" = "remove" \) -a -L /usr/doc/libstdc++2.10-dev ]; then rm -f /usr/doc/libstdc++2.10-dev; fi install-info --quiet --remove iostream$pkg_ver -- Note how $pkg_ver is not set. Looking at the postinst, there is a value, and no variable. This appears to be a problem with some file munging in debian/rules, but I haven't checked there.
