Xcode - SenTestingKit not found

Question

Hi all,

I have an issue that popped up when I upgraded my version of xcode. I use unit tests, and I now when I try to import SenTestingKit (#import <SenTestingKit/SenTestingKit.h>), I get this error: SenTestingKit/SenTestingKit.h: No such file or directory.

I have looked at my build settings, and I have the following configuration options:

== Linking ==
Other Linker Flags: -framework Foundation -framework SenTestingKit -framework UIKit
Prebinding: No

== Search Paths ==
Debug Configutation: "/iphonesimulator4.0/Developer/Library/Frameworks" "/Xcode4/Library/Frameworks"

I've checked /Xcode4/Library/Frameworks, and the SenTestingKit.framework/ directory is there.

So what am I missing?
