You didn't mention what command you used to update, so the first step is to 
run:

# emerge -vauDN --with-bdeps=y @world

The key options there are N, which will rebuild all packages whose use flags 
have changed (usually from profile updates), and --with-bdeps=y which will take 
into account build depedencies. I only use the latter when there's conflicts 
because it slows portage down. I just had the same libcrypt conflict that 
you're having and that fixed it.

If that fails add the --backtrack=30 as advised by portage and post the output 
if there's still blockers.

I did noticed that you have the libreoffice-bin package. If your using an 
unstable boost sometimes I've found that the conflict is unsolvable and the 
only solution is to add --exclude=app-office/libreoffice-bin until they release a 
new version (which can take weeks) or switch to app-office/libreoffice.
