[Bf-committers] No Sound in BGE on OSX, Can someone update dep's?

Sun May 3 20:54:30 CEST 2009

Hey there,

I rebuilt the alut library for osx a few days ago but I still haven't  
had a chance to test it.  In theory it should just link and work  
against the OpenAL framework from the osx sdk after the include paths  
get fixed.
