Use the system provided openAL framework, it's what I'm using for the port of Amnesia:: The Dark Descent that just got released last week. And I'm building that for PPC and x86 architecture.

I can run the program from Finder, the sounds don't play correctly ( some kind of fuzzy noise covers the sounds ). This may be a problem with my code that imports the wav files ( that works under windows ) or another compatibility problem. But I'm using gcc 4.0 as a compiler and xCode won't let me debug or run the program because its says the debugger doesn't support ppc. So I can't debug :-(. 

Yes, one of the lovely issues of trying to develop PPC apps on an intel mac..  You need to have a PPC mac to debug on (you can remote debug from your intel mac though Xcode though)..  what you are probably hitting is an endianess bug.. you need to swap your data on the way in from the file then it'll sound correct. So debugging on the i386 wouldn't help you there as i386 is little endian as well.

If you are running  OS X Tiger, then the included OpenAL framework (in /System/Library/Frameworks/OpenAL.framework) includes both the i386 and PPC binaries.    In leopard(possibly), but defintely in snow leopard and higher it includes all 3 archs.  i386, ppc, and x86_64. So there is no need for any building of OpenAL, just include the system OpenAL framework.
