 Replying to [comment:2 devans@…]:
 >  * Would you look in
 /System/Library/Frameworks/AppKit.framework/Headers/NSEvent.h and see if
 NSEventPhaseMayBegin is defined there?

 Done. It is not.

 >  * What version of Xcode are you using? The recommended version for 10.7
 is Xcode 4.6.3 which can be downloaded
 [http://adcdownload.apple.com/Developer_Tools/xcode_4.6.3/xcode4630916281a.dmg
 here.]

 I'm using Version 4.6.3 (4H1503).
