Many upstream bugs fixed of this 3.6 release. I managed to just remove the first two patches of 3.6.0.2 ebuild and compile as 3.6.1.2.ebuild using: app-office/libreoffice-3.6.1.2::maci USE="branding cups dbus graphite gtk java opengl svg vba webdav xmlsec (-aqua) -binfilter -binfilterdebug -eds -gnome -gstreamer -jemalloc -kde -mysql -odk -postgres -test" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer -nlpsolver -pdfimport -scripting-beanshell -scripting-javascript -wiki-publisher" 0 kB So I didnt try pdfimport. An I experience enabling USE gtk disabling USE kde shows up libreoffice much better running kde. I wonder what about it is this USE flag kde ...
Seems this was fixed in the meantime.
