'purge' fails after recent Xcode update?

I'm curious if anyone else has encountered this issue...

 

I noticed today that executing the 'purge' command in Terminal returned this:

 

dyld: Library not loaded: /System/Library/PrivateFrameworks/CHUD.framework/Versions/A/CHUD

  Referenced from: /usr/bin/purge

  Reason: image not found

Trace/BPT trap: 5

 

I understand it's whinging about the missing CHUD framework; why is it missing?

 

The only cause I can think of at the moment is the recent Xcode 4.6 update and it's CL Tools (updated both today).

 

Before I go grab the 2009 CHUD Tools .dmg from the dev resources I just want to know if this has been encountered elsewhere.
