At least until this Bug

https://bugs.gentoo.org/show_bug.cgi?id=371099

is resolved (sog) sage requires ~numpy-1.5.1

I'm not sure exactly the impact on your system of masking >=numpy-1.6.0 but you
could try that and see what emerge -puDNv world gives. I don't see which
component, if any, of couchdb is pulling in numpy or where else numpy is
needed on your system. Oh, and you will also have to mask >=pexpect-2.4
