Not sure what dependencies were broken or why, but you seem to have installed at some point various versions of zlib, which were thereafter uninstalled in a somewhat unclean way. Next time you can use quickpg to create a binary of an installed package before you unmerge it. This could help you recover from unintended breakages. Portage *should* remove a package completely and cleanly, while by deleting files manually you could mess things up and leave portage in a messy state. If unmerging a package does not uninstall it cleanly, this means there's a bug in the ebuild and it would merit posting a report in BGO. Otherwise, emerge @preserved-rebuild -v -a and revdep-rebuild -v -- -a ought to (re)emerge any missing dependencies or dependencies which need to be rebuilt. -- Regards, Mick
