Do you have guilt installed locally ? You are likely using the
native guilt. To keep patch lists separate on a per-branch basis
and to be able to capture them on th meta-branch, there are some
patches to guilt that move the patch directory location.

Are you working on top of linux-yocto-3.2 ? Or some other 3.2 tree ?
