indexes don't get created using mongorestore.

I've only experienced this consistently on my development machine, which is osx 10.6.5. in linux, I've seen indexes restored correctly. this is a mongodump on linux, copied to my osx machine, then mongorestore'd.

below is the output from running mongorestore:
