How did you start this project?  It looks to me like your bitbake/Yocto
environment hasn't been set up completely.

These steps can get you started:
   % . <YOCTO>/oe-init-build-env my_yocto_build
This will create a build tree called `pwd`/my_yocto_build.  You can put the name
of any directory here.  After the above step, your shell will change to that directory.
Now, edit 'conf/local.conf' to match your needs.  Then you can build your image:
   % bitbake core-image-minimal

Please try exactly these steps and see if it helps.
