>Description:
I rececntly switched to kgsrc-2008Q2 on my Mac. This breaks the build of 
libsndfile which was building fine before.
>How-To-Repeat:
Build libsndfile on a Mac.
>Fix:
Apparently the problem is caused by patch-ac in the patches folder.
Applying this patch causes sox to try and enable OSS on a Mac which does not 
work. Missing include files cause the build to fail.

Building libsndfile without patch-ac does work, though.
