Gentoo Advisory: Upgrade to expat2 breaks system
Gentoo users running GNOME will probably encounter trouble when upgrading to the latest version due to a major revision change in expat (from 1.95.8 to 2.0.1).
The procedure for upgrading that works for me is as follows:
1. emerge -uav world and note any blocked packages.
2. unmerge the blocked packages (don't worry, the updated versions will be installed later since they're GNOME core dependencies.)
3. emerge -uav world, check your USE flags and verify that the new versions of the blockers you just unmerged are in the list.
4. When you encounter a build error (for me a config error regarding XML_Parser) run revdep-rebuild. Revdep-rebuild will churn through a couple of packages and then fail. Run rm /root/.revdep-rebuild*.?_*
Repeat 3 & 4 until system update finishes and revdep-rebuild reports no broken packages.
