an emerge @preserved-rebuild for !!! existing preserved libs: >>> package: media-libs/freetype-2.3.7 * - /usr/lib64/libfreetype.so.6.3.17 >>> package: x11-libs/pango-1.20.5 * - /usr/lib64/libpangoft2-1.0.so.0.2002.1 generates 89 reinstalls, including openoffice, which i was not able to emerge in one row with resumes. i had to emerge something else after about 80 of 89 was built. and had to rerun emerge @preserved-rebuild, which recalculated the 89 reinstalls. portage should set a list of packages to be rebuilt by @preserved-rebuild, and not recalculate it next time, if it is already built since last set.
This sounds like a dupe of bug 230257. I'm having roughly the same problem btw.
