Emerging evas (1.0.1 or 9999) after updating glib from 2.26.1-r1 to 2.28.8, it complains about missing /usr/lib64/libgobject-2.0.la. glib-2.28.8 did not install this file no more, while it exists in the image directory (/var/tmp/portage/dev-libs/glib-2.28.8/image/usr/lib64/libgobject-2.0.la) in the ebuild, I read # Completely useless with or without USE static-libs, people need to use # pkg-config find "${ED}" -name '*.la' -exec rm -f {} + after commenting that line, evas-1.0.1 did install.
Use revdep-rebuild/lafilefixer.
