I'll have to defer to Stephan Huber and Eric Wing on getting XCode
projects working for 2.4, hopefully they can get fixes checked in time
for 2.3.10.
There is always the CMake build which you could fallback on too.

You'll need to add the above define into the build to select the right
header types to match the libs you've built.
With a CMake build it's possible to add this in, I recently added the
below script section to VirtualPlanetBuilder/CMakeLists.txt which uses
osgversion to find out details on the types built into the osg library
itself. This script addition automatically selects the right types
for the osg lib being linked against.
This is really yet another reason for using CMake over XCode, as
Stephan says, it really is time we moved entirely across to using
CMake on all platforms. OSG-2.4 will be the last release with
separate XCode projects as part of the core distribution.
