Hello, Friend! This is a repost of my previous patches that I'd like to see applied soon. I've also fixed the commit messages.
Short description: 1. fixes Portage not to replace non-installed 'dev-foo/bar:=' deps with plain 'dev-foo/bar'. This affects e.g. || () dependencies where the remaining branches may have referred to non-installed packages. By keeping the := operator in those dependencies, @changed-deps is able to correctly match old and new depstring. 2. adds a @changed-deps set to rebuild packages for which dependencies have changed (ebuild compared to vdb). 3. adds a repoman check for dependencies that refer to packages that have more than one slot yet do not specify a slot explicitly or use a proper slot operator. This is meant to help fixing mistakes like: dev-libs/openssl -> dev-libs/openssl:0 [:0.9.8 comes with no headers] -- Best regards, Michał Górny
