updating Three20 gives me path-related compiler error

[Zak]

I'm getting an error after updating:

error: /Users/zak/Dropbox/xcodeProjects/MyApp/../facebook-
three20-527051a/src/Three20.bundle: No such file or directory

The old Three20 was in the facebook-three20-527051a directory, which I
deleted. My new one is facebook-three20-b16d67c
