Running pax-mark in pkg_postinst() is wrong, it changes installed files and produces false positives in 'equery check' when $PAX_MARKINGS has PT (current default). Now stable tar supports xattr, so PAX_MARKINGS=XT will work fine when using bin packages too. $ equery check libreoffice * Checking app-office/libreoffice-4.1.2.3 ... !!! /usr/lib64/libreoffice/program/unopkg.bin has incorrect MD5sum !!! /usr/lib64/libreoffice/program/soffice.bin has incorrect MD5sum 3280 out of 3282 files passed
Fixed in the live ebuilds, will be in the next version bump
