ah i just realized that version 0.1.2 has been tagged 2 days ago.. i 
think it's a good idea to update the fink package.

i just tried to build freenect and pix_freenect against libfreenect 
0.1.2 from fink without any problems. the externals work.


i didn't have any problems so far with the latest libfreenect version 
and it should be backward compatible since the first official release.
just audio isn't working by now under osx but the fink package isn't 
built with audio support anyway (what is fine for the moment).

by now i have libfreenect and libusb included in the build folder.
would it be better to remove those and "force" users to install those 
via fink?
