Having trouble compiling Three20 sample TTCatalog

Question

I downloaded from git a copy of the latest three20, and I keep running into errors when I try to compile the sample code in the folder.

Undefined symbols:
  "_UIApplicationDidEnterBackgroundNotification", referenced from:
      _UIApplicationDidEnterBackgroundNotification$non_lazy_ptr in libThree20UINavigator.a(TTBaseNavigator.o)
     (maybe you meant: _UIApplicationDidEnterBackgroundNotification$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status

I'm running Xcode 3.2.3, compiling to Debug simulator 4.0

Any ideas on what to do?

I've compiled once before a while ago, before I forgot about it. Can't seem to recompile anymore.

Thanks.

Try the usual suspects of Clean All Targets and XCode/Empty Caches, and/or restart XCode.
