Right now, if I emerge a bunch of packages, for example
emerge lynx kde gnome mplayer mozilla-firefox
and lynx has a compilation error, the entire emerge fails. My "feature request" is that there be an emerge option, for example --endure (-E) so that if you do
emerge -E lynx kde mplayer mozilla-firefox
and the build of a requested package or its dependency fails, portage will calculate which of the remaining requested packages don't have the failed package in their dependency tree, and build those.
This is something that we can easily account for when we're adding support for parallel builds (bug 147516).
