(In reply to Dirkjan Ochtman from comment #0) > emerge -uavD I think -u won't work unless there is actually a package to upgrade in preserved-rebuild set. What is the output of: # emerge -pv @preserved-rebuild ?

You changed some use flags for gd. This means that after reinstalling it, it wouldn't satisfy dependencies of some installed packages. (flags: fontconfig,jpeg,png,truetype)
Okay, well, can we transform this bug to be about improving the error message? !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: "Multiple package instances" is pretty vague in this context. Can we have it say something about USE flags specifically?

Can we have it > say something about USE flags specifically? Well, if you keep reading it tells you that there are two instances of gd. An ebuild from ::gentoo and an installed package. It also tells you that there are some dependencies which can only be satisfied by the installed package. If you view that in a terminal with color support, it even highlights the use flags that cause the problem in the dependency atom. Anyway, if you have some suggestion to improve the message, go ahead.
