It's still broken (just pulled and built). Now I get the error:

 No search engine defined for (nnimap "gmail" (nnimap-address
 "imap.gmail.com") (nnimap-server-port 993) (nnimap-user
 "raman@google.com") (nnimap-authenticator xoauth2) (nnimap-expunge
 always) (nnmail-expiry-wait immediate) (nnimap-streaming t)
 (nnimap-stream ssl))
 Could you perhaps move your changes to a separate branch  where we can
 debug things and restore the previously working world?
