Looking at the ebuilds, both gnupg-1.4.7-r1 and gnupg-2.0.7-r1 occupy
SLOT 0, which is the cause of the initial error. However,
squirrelmail-1.4.10a-r2 depends explicitly on gnupg-1.4*, while
spamassassin only requires gnupg (any version). What you can try is to
emerge -1 =app-crypt/gnupg-1.4.7-r1, then retry your emerge -puvD world.
This should satisfy the dependency on both packages.
