If you do --pretend --verbose, does it show the changed USE flags for the packages? Not sure if 'world' does this, but you could try the individual packages that you expect to be rebuilt. IIRC, it appears in green (on a colour screen...) with a + and * next to the USE flag.
emerge -uD --pretend --verbose --usepkg --newuse world does not show the change in USE-Flags. However it installes some software cased by the new USE-Flag (in my example samba). I run "equery hasuse my_new_flag" and the merged this pkgs with:
emerge -1 --usepkg --pretend --verbose pkg_spec_from_equery then the change in USE-Flags are showen and my _correct_ binarys are used.
Not a solution, but hopefully it'll add insight.
it seems we are actually 2 who worked at the same time with binarys :-) Sascha. -- gentoo-user@gentoo.org mailing list
