 My testing shows gtk3 +quartz builds correctly on 10.8+.  Unfortunately, I
 don't have a machine capable of running 10.7 to test that version so I
 have no way to verify your results.

 However, according to Apple's Appkit Framework
 [https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSEvent_Class/#//apple_ref/c/tdef/NSEventPhase
 NSEvent Class Reference], the NSEventPhase* constants (including
 NSEventPhaseMayBegin) were introduced in 10.7 so this should build
 correctly on 10.7 although I would expect it to fail on 10.6 and earlier.

 Questions:

  * Would you look in
 /System/Library/Frameworks/AppKit.framework/Headers/NSEvent.h and see if
 NSEventPaseMayBegin is defined there?  The definition should look
 something like
 {{{
 #if MAC_OS_X_VERSION_10_7 <= MAC_OS_X_VERSION_MAX_ALLOWED
 enum {
     NSEventPhaseNone        = 0, // event not associated with a phase.
     NSEventPhaseBegan       = 0x1 << 0,
     NSEventPhaseStationary  = 0x1 << 1,
     NSEventPhaseChanged     = 0x1 << 2,
     NSEventPhaseEnded       = 0x1 << 3,
     NSEventPhaseCancelled   = 0x1 << 4,
     NSEventPhaseMayBegin    = 0x1 << 5,
 };
 #endif
 }}}

  * What version of Xcode are you using? The recommended version for 10.7
 is Xcode 4.6.3 which can be downloaded
