Hi,

I'm trying to build from source on OSX. I've followed the instructions in build-osx.txt, and everything's gone well up to the wxWidget build.

I'm getting the following errors:
../src/osx/cocoa/evtloop.mm: In function ‘NSUInteger CalculateNSEventMaskFromEventCategory(wxEventCategory)’:
../src/osx/cocoa/evtloop.mm:78: error: ‘NSEventMaskGesture’ was not declared in this scope
../src/osx/cocoa/evtloop.mm:79: error: ‘NSEventMaskMagnify’ was not declared in this scope
../src/osx/cocoa/evtloop.mm:80: error: ‘NSEventMaskSwipe’ was not declared in this scope
../src/osx/cocoa/evtloop.mm:81: error: ‘NSEventMaskRotate’ was not declared in this scope
../src/osx/cocoa/evtloop.mm:82: error: ‘NSEventMaskBeginGesture’ was not declared in this scope
../src/osx/cocoa/evtloop.mm:83: error: ‘NSEventMaskEndGesture’ was not declared in this scope

repeated a few times in other functions.

I'm much more experienced at Windows development than Mac development, so any suggestions would be greatly appreciated.
