I recommend upgrading to dpkg-1.13.11 to fix this problem. From app-arch/dpkg/Changelog: 29 Aug 2005; Mike Frysinger <vapier@gentoo.org> metadata.xml, +dpkg-1.13.11.ebuild: Version bump to fix md5sum manpage collision. This newer ebuild has already been promoted to stable on x86 and ppc, and the others will probably follow soon (Bug #134279)
