Right.  I was asking about the case of building from git -- there I'm
using ./autogen.sh.  Is that not sufficient?

In any case, for now, the patch I posted handles the problem.

Here's the nsswitch.conf:

  passwd:         compat
  group:          compat
  shadow:         compat

  hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
  networks:       files

  protocols:      db files
  services:       db files
  ethers:         db files
  rpc:            db files

  netgroup:       nis
