(In reply to Alexander Tsoy from comment #0) > SLOT=5 was recently added to provide libncurses.so.5 for dropbox :) See bug > 557472 To be more precise, all ncurses ebuilds were converted to SLOT=0. But then SLOT=5 was reintroduced for dropbox.
Guys, do you realise the extent of the damage latest changes around ncurses has caused? See this topic for example: https://forums.gentoo.org/viewtopic-t-1027536-highlight-ncurses.html In my case, I can say I was lucky, for me it was sufficient to unmerge mplayer (which I will miss!) and re-emerge ekg2 with -ncurses flag and the problem went away. But in general, the problem like this one may result in bad perception of Gentoo as a whole.
Ooops.. I just realized that dependency conflict was caused by subslots recorded in vdb (see bug 558856). I was able to update world with the following command: # emerge -avuDN --changed-deps --exclude sys-libs/ncurses @world But anyway dependency 'sys-libs/ncurses:*' is incorrect and should be updated to 'sys-libs/ncurses:0=' since SLOT=5 doesn't install headers.
Should be fixed in net-mail/mailutils-2.99.99. Thank you.
