filed with upstream dpkg maintainers; their bzip2 incorrectly utilizes zlib
defines in error checking when it should be using bzip2 defines ...

just for easier reference:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=410605

the URL field of the bug report is already set ...

apparently upstream fixed this in dpkg-1.14.0

1.14.12 now in the tree
