Carbon, as a framework, is available to 64-bit apps, but large portions 
of it have been removed (almost all the GUI stuff, some other deprecated 
APIs that have lived since Classic Mac OS)...but Carbon holds all the 
CoreFoundation APIs and lots of other important system facilities, and 
they haven't left.

PhysicsFS 2.0.2 definitely works in 64-bit:

     [icculus at caridad ~/projects/physfs/cmake-build]$ file test_physfs
     test_physfs: Mach-O 64-bit executable x86_64

     [icculus at caridad ~/projects/physfs/cmake-build]$ ./test_physfs

     test_physfs version 2.0.2.
      Compiled against PhysicsFS version 2.0.2,
      and linked against 2.0.2.

With a little effort, you can get the Mac builds of PhysicsFS to use the 
Unix/POSIX code and no Carbon calls at all, if you really need to.

...wxWidgets, and thus that silly test app, uses Carbon for its GUI and 
will absolutely fail to link a 64-bit app unless you use the bleeding 
edge, Cocoa-based wxWidgets.
