This is an auto-filed bug because app-office/openoffice-bin installs files with unresolved SONAME dependencies. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info.

These are all from optional runtime dependencies. libavmediagst.so I think needs gstreamer:0.10 which is gone from the tree (bug 592850 and bug 668102). A possible workaround would be to install these filed conditionally.
I meant bug 529850 in the previous comment.
app-office/openoffice-bin is now last rited.
removing.
