Node SDK fails on Mac 10.11 (El Capitan)

Tried to npm install 2.0.12:
(also note node 4.1.1 and npm 2.14.4)

Also tried 2.1.2 but it gives a client timeout on every operation

{ [CouchbaseError: Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout]
  message: 'Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout',
  code: 23 }

Looks like this might explain it: Eventual support for io.js/nodejs v4.0.0 (NAN >= 2.X)
However it doesn’t explain why node.js SDK 2.1.2 doesn’t connect.
