 should compile your application the same way.
 
-Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
-(even if you target back to 10.6 systems). PowerPC support for Mac OS X has

 To use the library once it's built, you essential have two possibilities:
 use the traditional autoconf/automake/make method, or use Xcode.
