When building TextEditor, you shouldn't need the Mac variants (so, you should just need "OmniBaseTouch" instead of "OmniBase", for example).

As for the SenTestingKit issue, it looks like I added a reference to that under /Developer/Library/Frameworks/SenTestingKit.framework in the TextEditor project (the default Xcode install location). You could change this to refer to it via your '/Xcode 4' install location, or try to use one of the variables ("$(DEVELOPER_DIR)" or the like).

But, longer term, we'll probably stop using SenTestingKit since it isn't available on devices unless the device has had its "Use for Development" bit flipped. In our current internal builds we have these tests only running on the Mac, but we'll probably be switching to GHUnit or one of the other testing frameworks that we can actually build from source.
