this is gcc4 not finding libc++ on 10.4 when linking C files calling  
a C++ library.


unfortunately,  between gcc4, gcc3.3, 10.3.9, 10.4, version of xcode,  
player and international  options, dynamic or static libc++ and some  
changes
  in the system frameworks, There is not a single patch that will  
insure compilation in all cases with scons. i passed a lot of time  
trying
and failed. I suppose phases of the moon is also a factor.

Thought, usually it is more make than scons which is dificult to  
configure.

First be sure to use the precompiled openal in lib/darwin-8.0.0- 
powerpc and not the one in   darwin-6.1-powerpc
in the same idea, check that your openEXR lib is a 10.4 one.
do a scons clean if it is not the case.


then try to define the following in your user config.py :

CCFLAGS = ['-pipe','-fPIC','-funsigned-char','-fno-strict-aliasing',  
'-fpascal-strings', '-fexceptions']
CXXFLAGS = ['-pipe','-fPIC','-funsigned-char','-fno-strict-aliasing',  
'-fpascal-strings, '-fexceptions']

lastly try to define LD= 'g++' in your user config file, works in  
many cases
