Make a function 

// native_pixmap_client.h
OZONE_EXPORT
scoped_ptr<NativePixmapClient> CreateStubNativePixmapClient();

// native_pixmap_client.cc
class StubNativePixmapClient {
  // ...
}

scoped_ptr<NativePixmapClient> CreateStubNativePixmapClient() {
  return new StubNativePixmapClient;
}

and use that for platforms that don't implement it.

Done.
